Full Momentum BONUS Episode 31 Multiple Opening Analysis

[Music] welcome to full momentum in HC Raz vodcast I'm your host Ben Cary and here joining me on a special bonus episode uh this is a little bit mid Monon we've been trying to do these things on a monthly basis but we had a topic that we thought was worth getting out there uh for folks to to learn a little bit about and for us to have a quick discussion on today Chris so thanks for hopping on on short notice bonus bonus content material today that's right that's right so it's G to be a quicker than uh than usual um podcast we're not going to go through listener questions we don't have any special guests today's uh episode it's all going to be uh focused on on a on a short little technical topic here but before we get into that I do want to give a quick shout out for those of you who just watched the new uh intro video that we have attached to the video podcast very cool awesome job uh shout out to clench M's marketing team led by Jill chromer who uh who kind of is our our captain of this ship um she had the idea to spruce up the intro and I think it turned out really really cool Chris yeah Jill's The Wiz are behind the scenes here and she takes care of us and and makes sure everything runs smoothly here and um she and her team did an awesome job on that intro Let to say the music is the same which we're we were debating a little early on should we yeah should we mix up the intro music it's the same music uh which by the way if you haven't heard our discussion on this in earlier podcasts that is Gary Bruner the father of HEC Raz playing the guitar on that song um and me playing drums too and so uh so there is a tie-in and so we couldn't really abandon that we had to keep it plus I like that song too it's really cool it's an original song written by Gary and uh he gets all the credit for that and I just kind of went along for the ride playing the playing the drums with him there but the video Change Up is really cool uh it's awesome stuff that our marketing team did so thank you Jill and Taylor and gr for that that's really cool yeah absolutely let us know what you think about the new video intro and whether you want to hear us change up the music I think most people are probably pretty still into the music but let us know if you want to hear a different tune to that video yeah and I would like to know from everyone too if Gary and I uh allowed Ben to join the band what instrument would he be playing that would be yeah I could see you I could see you on uh you know maybe the tambourine a little bit yeah I could do that I could uh I think I I got about as much skill as required for maybe those little just shakers shakers I think I could I think I could keep a rhythm on that but that would be probably as far as I could go if I if I have a few adult beverages I might I might sing I could sing oh oh oh yeah yeah see we could add some uh vocals to that intro there you go and that'll be your contribution all right we'll have to think about how we how we'll do that very cool well let's jump into today's technical topic before we do I just want to give a quick um thanks to our sponsor for today's episode and that's our firm kenman Associates who is known throughout the industry as a firm that provides practical solutions to complex problems affecting energy water and the environment you can learn more at Klein Schmid group.com you may also notice that in the upcoming weeks I think there's a plan to to rehash the km. group.com website so be on the lookout for a new Fresh interface there uh as you're going to check out different content that we have posted on our website so uh today's technical topic is about uh is framed around the idea and the ability to model multiple openings for 1D structures um this is a feature that's made available to you um so to to provide a little bit of context and to frame this when you add a uh 1D Bridge into an HC Raz model you have the ability to not only simulate the bridge opening itself but to also include uh coverts um in that structure overall so it ends up being kind of a a structure that has multiple openings and as part of that the recommendation or what I thought was the recommendation in uh the manuals is to use the multiple opening editor within HC Raz which allows you to kind of spe spe ify the different opening types that you might have within a single 1D Bridge so if you have one bridge and one Culvert you might have two openings that you specify if you have one bridge opening and a couple different culs you might end up with three four five multiple openings um so there's a lot of flexibility there and it allows the program to compute how each of those openings function separately because as we know covert flow is going to be a little bit different than Bridge flow and specifying those multiple openings allows the program to to simulate that as as accurately as possible now this is where we get into the interesting part of this discussion and something that I learned in some of the discussions I've had with You Chris over the last couple weeks on this and that is not only is this a recommendation for using a software using the HC rout software when you're simulating multiple openings at a 1D Bridge it's actually required if you want the program to really function correctly um and so I'll turn it over to you you can share a little bit more about um you know why that is and and what happens if you don't end up using that multiple opening uh option yeah so this this is for Bridges specifically and culverts and uh for those of you who've done Bridges and CS in 1D modeling you know that there is a button called Bridge covert so they're actually added in the same place so let me get my screen shared here so I can kind of talk you through um what I'm thinking about but um if you do have a crossing and that's the term I like to use to kind of Encompass both Bridges or coverts or a combination like a multiple opening but if you have a crossing and you want to add that into your model you would go to the bridge Culver button that you see right here and this is actually the this is the Beaver Creek single bridge data set that comes with the software in fact if you were to download the example data sets that come with hecz when you install it you'll see all of these folders here and in the applications guide you can find a bunch of different types of models here and there's this one called Beaver Creek and it's a it's a bridge model and that's the one I started with here to do this demonstration so this may look familiar to you if you've been in some of those applications guide data sets but anyway if you want to add in a bridge or you want to add in a c you would click this button right here for 1D model and you get the bridge cover data editor here you can see we just have a single Bridge opening this is the Beaver Creek Bridge as it comes with the software now let's say we want to add a covert here okay maybe we want to put in a relief covert over here to add a little bit more capacity um for water to pass this Crossing we can do that you would just go down to the cul button and then add in the necessary information for your covert or CTS and that would effectively add in a covert off on the side now I've done that in this example project I'm going to switch plans from bridge only to bridge with relief covert and you can see what I did here now I've got this relief covert over here on the side and if I zoom in a little bit you can see it better here's the bridge opening is still there I've got the relief Culvert I did some tweaking of the ineffective flows so I don't have in infective flows blocking my Culvert so I had to kind of open them up where the Culvert is but effectively now I've got a bridge and a relief Culvert in here and so this gets to the problem um and let me show you how uh I kind of discovered this issue if you run this plan with the relief CT and compare it to the plan with the bridge opening only what do you think would happen or should happen to the water surface Ben by adding in this relief cul and I mean the water surface just Upstream of the crossing yeah so you you would assume that if you add another opening it's additional conveyance you would expect the water surface elevation Upstream of the opening to drop slightly is there's additional water being passed Downstream that's right it's aady model assuming that the water surface elevation is below the top of the deck uh well I guess even if it's not below the top of the deck it would still probably drop that's right yeah you're just adding more places for to get through this Crossing and so it's it's more efficient it's um got more capacity to pass flow and so for the same flow amount you would expect the water level to drop however when you run these two plans this is the uh the plan with the relief Culvert I'm going to open up the other plan so we can see it together the same plot so Bridge only Bridge with relief covert these are the two I'm looking at now if I look at the relief covert look what happens it actually jumps up significantly I mean we're talking three four feet of rise and this is actually an example or this is a recreation of something I saw in an actual FEMA model that has been um part of a particular Community for over 20 years they had this wrong answer because of this very reason they put in a culvert and a bridge opening and it gave him the wrong answer so why did it give him the wrong answer yeah and and let me before I get into that let me just take a step back because this this was a big deal and I think this was really the the reason that we wanted to get this information out to folks because what we what we realized and having this conversation is one you know like I was not aware of this limitation so I can just put my hand up and say you know I did not know that this would occur if you don't use multiple opening analysis you had a CT you're going to have an issue with Water Service elevation not doing what you expect um but in addition to that this was a again a published effective FEMA model being used for Community insurance purposes yeah and so with the realization that that sort of issue was out there as an effective FEMA model went through review in theory and wasn't caught we thought it'd be really helpful to share the why behind this so that people can avoid the situation and you know you know not put themselves in a position where they're putting out results from a model that's not performing correctly yeah super important um we don't want people to make this mistake um now you can add multiple culs it's fine I'm not saying you can't do that you can have multiple bridge openings you have can have a combination of as many of those openings as you'd like in a crossing of course Ben and I always like to talk about keeping things as simple as possible too but hey if you got all these different uh covert openings and brid openings yeah you can put them in there but there's one more step that you have to take now if you read the manual the manual when it talks about multiple openings it says specifically in the manual you can use the multiple opening analysis which is this button right here it doesn't say you shall use the M multiple opening analysis but Ben and I are here to tell you you shall use the mulle opening analysis okay uh if you have a CT or coverts and a bridge opening in the same Crossing you have to use this okay so what is it so it's this button right here that says multiple opening analysis when you click on that you get this table right here and so in order for Raz to figure this out you have to Define areas of influence of these different openings now with just two different opening types it's pretty easy to do but it gets more and more difficult the more opening types that you have to segregate out here but with only two um we have to fill out this table to tell Raz okay what part of this cross-section belongs to the covert and what part of the cross-section belongs to the bridge opening that's what Raz needs to know to be able to determine the flow distribution how much flow is going through here versus how much flow is going through the bridge opening okay so instead of typing that out I'm going to open up the third plan that I have in here which is multiple opening actually actually before I do that I want to show you one more thing um this is another bit of evidence that that you can see that the um without using the multiple opening it's not working correctly if I go to the detailed table this is my plan that has both the bridge and the Culvert in it and you look at this closely now I know that I only have 10,000 CFS flowing through here because I set that up in the flow file if you look at the flow through the culverts 4913 s and then over here we have a weir flow of 95 8.63 uh trust me you don't have to get your calculator out but those sum up to exactly 10,000 CFS there's no flow listed here for the bridge in fact there's not even a a row for bridge Flow In fact when you add in a cart to your Crossing it now thinks it's a Culvert it doesn't even think it's a bridge anymore and it even changes the name to Culvert as you can see right there so effectively what's going on is Raz doesn't even consider this bridge opening anymore it might as well just be completely blocked out and that's why we get this big rise because now the only capacity we have through this CT or through this Crossing is through the Culvert or over the top as you can see now we have wear flow going over the top the bridge opening is not even part of the equation anymore now to to to I guess add a little bit of context to this conversation I think Chris what you just showed us in terms of what you saw with that model where this was an issue um you know this is why checking your results and not just the profile plots not just the cross-section plots but actually looking at the numerical output data is really important when you're qaq seeing a model because it might show you something that you're not expecting and that would lead you to have a better understanding of how your model is actually performing because if you look at just the profile plot or just the cross-section plot it doesn't look like that bridge opening has been filled in that it's not being considered there's really no way for you to know that you have to get in and look at the actual quantitative output data to to do that so hopefully everybody's doing that now but as we just said there are situations that uh in which that hasn't that hasn't happened so yeah so now getting back to what you should do in this situation go to the multiple opening analysis I'm going to open up that plan now that's my third plan here multiple opening and when I open this up you'll see that if I go back to the bridge cover editor it's the same thing I got the same covert same bridge opening here but I filled out this multiple opening analysis table you see right there okay and that's what these red Dash lines represent they represent these different zones of influence that I've established so that Raz can figure out how much flow goes through the covert and how much goes through the bridge opening these zones of influence they call them stagnation points because they sort of represent where flow as it's approaching the bridge will split you know the line of kind of the plane of um Divergence I guess is a way to put it where flow flow on one side of that plane will go through the bridge opening flow on the other side of the plane goes through the Culvert and so you're defining these planes these they're called stagnation points in Raz and you do that here in this table now there's a couple ways you could do that you can explicitly Define where that plane of Confluence or Divergence is or if you're not sure you can let Raz figure that out Raz will actually go through an optimization scheme and do an energy balance to figure out where that actual plane of Divergence or stagnation point should be and so for you to Signal Raz to do that you would actually overlap these zon so notice Zone one goes from the end of the cross-section to the edge of the bridge opening and zone two overlaps that it actually starts at the edge of the Culvert and goes to the end of the cross-section so we have this overlapping Zone here as we've defined it in this table okay notice station left and right for the Culver is zero and 450 but station left for the bridge is 205 so it starts back next to the Culvert okay yeah important note on this and it's might be intuitive but it's very important that your multiple opening your first uh opening station and your last opening station need to cover the full um length of your of your structure if your last station uh for this structure ended at station 1500 when you went to run the model you would actually get an error because there's a portion structure that's not included so that's right that's right and it doesn't hurt to extend beyond like you see right here I've gone all the way out to St 2000 even though the cross-section really goes out to 1850 or so um so it doesn't hurt to go too far but you definitely don't want to go too short then you're going to have a problem okay so now we've set this up as an overlap and we're allowing the stagnation point to float and this is how the manual describes it the process of Raz figuring out where that stagnation limit is um and it does that with an energy balance now I could alter natively just set this up so that I forc the stagnation Zone to be or stagnation point to be at a specific location without having the overlap in which case Raz would not go through that iterative procedure and it would just accept how you've defined the different zones of influence but of course there's uncertainty we don't know exactly where that Divergence point is so let's let Raz figure it out using the energy balance and energy balance okay so that's all you have to do is fill that you do that for both the upstream and downstream sides and they could be slightly different depending on the configuration of the Upstream versus Downstream but once you've done that now Raz will actually consider each of these openings independently and figure out the flow distribution for both rather than leaving out a big bit of conveyance being this bridge opening here so let's go take a look at that result now I'm going to add in plan number three here I'll just add all three and now all of a sudden you [Music] see okay Bridge only is down here this is the one that's wrong bridge and Culvert and this is the multiple openings very similar to the bridge only which is expected because that Culver is pretty small but if I zoom in close you can see that with the multiple opening the water does drop slightly because it has that additional covert in there and there's your original Bridge there's Bridge with culbert so yeah and that that I just want to point out that apparent jump in water surface elevation that's shown in the multile openings uh my understanding Chris is that's not uh that's not a real computed water surface elevation that's more of an effect of the multiple openings um because when I've done multiple opening analysis I've seen that we kind of ran it down a little bit and and were able to confirm that um that's more uh of a visual result of using the multiple opening analysis not a computed water surface well this is are you talking about right here yeah that because if you compare the bridge only to the multip opening it's that jump that jump in water surface elevation we'll call it yeah no this is actually real and it's it's not that big of a jump I mean this scale is very distorted it's about a half a foot jump up but this is actually happening because now we have flow going through the Culvert and if I zoom in on this you can actually see this flow profile inside the cul is computed see these individual points these are actually computed inside of the covert so this is just showing you what's in the covert versus without the CT if I zoom back in with the bridge only there's no covert to go through it just goes through the opening so no I guess what I mean though is I think I think we can confirm this if you open up the crosssection output View and you look at the internal Bridge crosssection you will see a water surface elevation I believe that's lower than um what that jump up is um yeah so here's the multiple opening and it's showing it at 25.0 n which is which is which is right there yeah okay and then we have without the Culvert it's it's down here at 24.6 which is going to be guess right about here yeah so I guess as a followup to that why would the water surface elevation in the the bridge opening itself increase it's only slightly but why would it increase with that additional conveyance for the CT yeah because that's actually a really good question um in so you're talking about inside the bridge why it go up yeah because we have more capacity right of flow same amount of Q so your area goes up right so velocity is going to go down M right and when your velocity goes down your velocity head goes down so um that's going to force the water level up to hit the same energy level that's it yeah okay yeah yeah and so if we were it might actually explain this a little bit if we turn on the energy grade through here here you can see the energy right is well it's not the same because obviously you got the c in there uh oh let's okay so there's our Bridge there's our multiple opening the energy goes down a little bit but yeah the velocity is going to slow down because you have more low area through the bridge and that's going to push up the um or sorry yeah push up the water level slightly okay great thanks for that explanation yeah it's kind of a tricky thing like um you I see this a lot in thema models too where um let's say there there's a a interest in designing a new bridge and you want to make the bridge bigger right wider so it's got more capacity to push flow through it that's a common thing right um and when you run the model you'll actually find that inside of the bridge where you've got the bigger bridge opening the water level actually goes up inside of the bridge now when you go Upstream of the bridge it'll go down below the existing conditions right but inside the bridge because that area opens up water slows down the water level will actually rise there and so it gets a little bit tricky when you have a no rise analysis you have to or no rise condition you have to adhere to yet here we are inside of this bridge that's bigger and wider should reduce flood risk and it will but right inside the bridge you actually get a slight rise doesn't that is doesn't that only occur if you are in or if you're critical flow doesn't that have something to do with it well it's different so when you're in subcritical flow the water level will go up if you wide widen the opening right inside of the bridge um Upstream it will go down right but if you're in super critical flow it's the opposite yeah it will actually go down inside of the bridge but go um but also go down Upstream of the bridge yeah yeah okay yeah because I remember when we when I done encroachment analysis in the past sometimes you encroach on the channel and the Water Service drops and sometimes you encroach on the Water Service and the water service on the channel and the Water Service goes up and that all has to do with where you're at in terms of the critical flow regime yeah there was a way I remember doing this um I think in graduate school where you can use the minimum en or sorry the uh specific energy curve yeah at a cross-section and you can actually show like theoretically that happening and why it goes up for subcritical and down for supercritical in when you widen it out yeah yeah yeah okay well even interesting stuff yeah I was gonna say localized hydraulic discussion aside the bottom line is is by adding this multiple opening analysis it looks like you decreased your you know modeled water surface elevation by four or five feet from yeah from the incorrect answer here so if we zoom in here I'm going to turn off energy just to make it a little bit easier to see but here is the incorrect answer this is when we had both the bridge and the Culver but we're not using the multiple opening Technique we get a overestimation in uh energy loss here um and it's incorrect and when you use the multiple opening technique with the bridg and Culver it brings it back down in fact slightly lower than existing conditions Upstream of the bridge which is what you would expect yeah so by if you had not done this you would and you were using this water surface elevation from your model to design uh something or to in FEMA purposes uh uh establish a base flood elevation for insurance in a community area you would be overpredicting the Water Service potentially pretty significantly and I suppose depending on the size of the bridge opening you know if you had a larger Bridge with even more Opening space and had a small Culvert that you were adding you could even have a bigger difference in water service elevation yeah yeah it's it's very important use the multiple opening if you do have multiple opening types and what I mean by that is a bridge opening that's an opening type culs that's an opening type you might have covers over here and you'd probably want to separate that out as its own opening in the multiple opening analysis in fact there's a third type of opening called conveyance let's say that over here the roadway approach goes back down to grade and so I don't have this elevated roadway approach and I've got water up here and it's flowing over natural ground you can set that up as conveyance over there and so that way Ras will actually use the um conservation of energy energy for steady flow or conservation of mass and momentum for unsteady flow it will use that over here instead of using the bridge equations and the wear equation the wear equations for the specifically yeah would use the wear equation over here if you didn't split that out as conveyance uh in this case though because it's elevated it's probably acting more like a weir so uh I kept it that way but yeah you could conceivably add in another thing called conveyance and separate this out over here as conveyance instead of if you wanted to yeah I suppose if your road was really close if the if the top of your Bridge was relatively close to existing grade upstream and downstream of your Bridge Andor if your Bridge was very very wide you actually might be better to kind of split out uh even just a standard Bridge um to multiple openings where you have your Bridge uh opening and then you have your conveyance on the left and right of that flood plane yeah it probably would make a huge difference in terms of overall results but it might be a little bit more accurate just in terms of what equations rest is using to compute um energy loss yeah and this is very analogous we've talked about this before on this podcast um the sa 2D connection you know the use normal 2D equation domain or use the we equation yeah that's this is the same thing only for 1D instead of for 2D where you can basically Say Hey I want to treat this as normal in this case 1D equations instead of the wear equation and so when you have a lot of submergence on here it's going to be harder to use the wear equation and so you might actually get instabilities and you may not even get this optimization to converge and that happens sometimes with multiple openings by the way um when you set tell Raz to figure out where these stagnation points it has to go through this iterative uh optimization scheme to figure it out balancing the energy and sometimes it's not able to do it within I think it's 30 iterations and you'll get an error message yeah um and so then maybe you kind of tighten these up a little bit and see if that helps yeah a couple other warnings just having used multiple openings in the past uh just be prepared that especially if you're using multiple openings for many uh number of bridges the pre-processing time on multiple openings is uh exponentially more than a standard Bridge so uh just be prepared that the pre-processing time for running a model like this is going to take a very very very long time compared to what you're used to with a quick 1D model so just keep that in mind um another you know work around it I was just thinking of Chris and this obviously wouldn't be probably appropriate in most situations but if you didn't want to deal with multiple openings guess you could just model that bridge opening as a another Culvert right you could just treat it like a large box CT for instance um or or vice versa you can make this another Bridge opening yep yep good point yeah instead of a covert but but then it's going to use the bridge equations over here not the CT equations and so yeah you're right though that that would be a kind of a workaround uh another workaround is you could actually split this into two parallel reaches coming down here put a junction up here and a junction down here split it two parallel reaches One reach for the bridge opening and one reach for the cver on the side but that gets really messy takes a lot of work and effort yeah and then you have to deal with Junctions which I hate dealing with Junctions and then the last workaround corre correct me if I'm wrong is you could just convert this to 2D area and just simulate this bridge or this multiple opening with an sa 2D area connection and then that would take care of it for you right I'm glad you brought that up because I like where you're going because anytime you have flow that's kind of moving laterally and doing weird stuff 2D would do a really good job with that much better than 1D however keep in mind the sa 2D connection which is how you do Bridges and culverts in 2D can only have one opening type in it you can either do a bridge or you can do a culvert you can't do you can't set up an sa 2D connection like this at least not yet but if I go it would be a lot easier to set up two adjacent s2d area connections one for the covert one for the bridge then it would be to split the 1D reach up and add lateral structures and all that jazz so yeah and and I I kind of take it back you can't have culverts and a bridge opening you can mix culverts and Gates though in here but if you wanted to do a bridge you're limited to just Bridge notice there's no covert button in here yeah right but yeah that would be the way you would do it is you would split the structure up and you would have a bridge structure um that starts somewhere over here probably where that stagnation point is and goes to that side and then you'd have a separate s2d connection that's bumped right up next to it and um that's the one that you would use for the Culvert yeah perfect yeah so so I want to show you one other thing too yeah go ahead and um so when you look at your table of results the detailed table here and you do a multiple opening now you actually have a type called multiple opening but I need to open that plan I guess um oh I am open I am in that plan why is it not showing me that maybe I need to run it let's run it real quick again it's a nice thing about 1D right you do that pretty pretty fast there we go so now I can see multiple openings here and in the multiple openings detailed output table it actually breaks it up into the different openings so I can see here I've got CT and I've got 126 CFS through that I've also got my bridge which is opening number two and I've got 9873 add those together you get 10,000 and that accounts for all the flow going through this bridge or this uh Crossing good yeah sweet so to recap um because there was a lot of information there but the big picture takeaway here is if you read the manuals it appears as though using multiple openings uh using multiple opening analysis for having a cver and a bridge in a ond bridge is optional it's something you can do but based on what you found and based on what some of the uh issues that we saw with an existing effective FEMA model um it's not optional you really have to use multiple opening analysis if you're going to be doing a combined Wy Bridge with a cul opening there are some workarounds including converting that particular area to 2D um and modifying how you're representing those structures but if you're going to want to model a bridge Culver combination like we've shown in the example today you have to use multi beine analysis or you won't end up getting the correct answer for the Water Service elevation in and around your your Bridge yeah might be very wrong like we saw here yeah so use that multiple opening for Oney and I I guess another thing I'll mention here is wy's not dead yet uh Everyone likes to do 2D modeling but there is definitely a place for ond modeling still and if you get into it you got a Crossing with multiple opening types use the multiple opening analysis yeah absolutely and we'd love to hear from you if you if this was something that uh is new to you that you're going to start to implement into your uh HC Raz modeling practices let us know in the comments below if this is something that you've known and you're shocked that somebody like me didn't know this give me a give me a hard time about it in the comments let me know that I I should have read the manuals a little bit better um but we'd love to again just know if this was a helpful thing to it to uh let people know about or if this is old old news to to those using it so yeah and also in the comments let us know what you think about our new intro video Yeah and don't forget to uh let let us know what instrument Ben should play in in the heck rock band um and actually while you're at it what what should be his uh rock and roll nickname because uh Gary's was Van Bruner because he had the stylings of Eddie Van Halen uh and mine was sticks for obvious reasons so I'd like to know what Ben's rock and roll nickname would be awesome and his instrument last piece of Pary information before we leave for today just a quick reminder on our upcoming HC Raz webinar series uh Chris is actually going to be in Norway uh the month teaching HC Raz to the folks our friends over uh in Norway um but in the US we have a couple opportunities for you to sign up and take an HC Raz 1D 2D course with us um you can find this information on clench group.com under our knowledge Hub and the professional development courses tab if you click on that it'll bring you to this page and you can see there's a couple different options the first is going to be our live class in Atlanta Georgia which if we pop open that we can get the dates um for that class it's going to be a three-day course eight hours a day we're going to have lectures we're going to have uh technical workshops there's going to be a lot of opportunity for Q&A before during and after class that's going to run from September 12th 10th to the 12th again in Atlanta Georgia um the location is a little is TVD but we're going to have a final announcement on that shortly in addition to the 3-day inperson course we are also going to be hosting our annual HC Raz Pub and rub yeah in Atlanta believe it's going to be the evening of September 12th again final details to come out on that uh but if you're in the Southeast if you're in the Atlanta area would love to have you take this course with us as well as come and uh attend that that Pub and Grub and it'll be a great night of presentations regarding HC Raz related
