Creo Simulate Thermal Analysis

welcome once again to product one's youtube series uh today we are looking at thermal analysis inside creo simulator uh we have been showcasing largely structural analysis inside our structural analysis environment and today we are going to be pivoting onto what we regard as thermal analysis this is all inside creole simulate that comes with a creo parametric of course you need a license for clio simulator now let's discuss in terms of what is the melanesis so thermal analysis it's basically use to calculate thermal response of simulation model to heat loads and boundary conditions so there are a couple of things that you can actually do with it you get to see what's the heat transfer on your particular object and sometimes you might need to analyze a particular object structurally however there is about a heat involved if you think about what happens when you hit your brakes and your brake pads it's coming in contact with the actual brake disc it gets hotter and now you can take that what you call heat load into your structural environment as well so however today we're just going to be covering just the key basics we're going to be doing two types of structure of thermal analysis the first one will be steady state analysis which you're going to be looking at now so the first thing that we're going to be doing is applying what we call a heat load so i'm going to select a surface in which my heat will be applied and the biggest thing that one needs to remember is that heat is transferred in several ways inside thermal analysis one is what we regard as conduction this is predominant mode of heat transfer through solids and then the other one is called convection which is heat transferred through a surface and a moving fluid so we just doing just a basic uh conduction uh heat transfer in this instance so now that we've applied a heat load we now need to apply what we regard as boundary conditions so if you think about it this is the equivalent of constraints when you're doing your structural analysis so if we were to do now the boundary conditions obviously you have to select the magnitude of what we regard as your initial temperatures so remember when you take the pot you put it in on top of a of a hot stove that part already has a certain temperature all right be it room temperature it comes from the fridge you put it directly on it on a hot plate now what we're going to be doing is specify the surfaces in this instance that are not subjected to heat in the beginning all right so what we're going to be doing now we'll see how the heat will be transferred due to temperature difference so if we were to select these surfaces that's just about it so these are the surfaces that do not have a heat load assigned to them okay if we now where to start our thermal analysis we're going to be doing what we regard as a steady state thermal analysis so this is equivalent of your static analysis so let's give this a name let's call it hub all right um all that is left for us to do is run that thermal analysis so you will see this takes a couple of seconds and then you get the results which we will look at in a second so the beauty of this this is part of your normal standard uh simulation uh package uh however oh the the results are here now so if we were to look at the results for for this this is what we've got you have here an overview of how the heat will move from that certain point into the rest of the geometry okay so this might provide a little bit of insight whether you've got too much heat in one area or you need to make some modification or you need to have a fan or a blower whatever the case is now what we are going to be exploring next up is what we regard as a steady state thermal analysis what we've been having now is a normal standard static or steady state steady state thermal analysis what we're going to be doing now is what we regard as transient thermal analysis so if you think about it what happens if you've got a structure like this and somebody is going to be having a moving heat load typically when you're welding something that will be a typical scenario here so what you do inside creole uh simulate is you go on to the demo mode and then you do a couple of things the first one is obviously you apply the heat load for the sake of time i've already applied my boundary conditions for this particular scenario so the first order of business in this instance i'm going to say i want my load to actually act on a curve so that's the curve in which will be subjected to heat and this is not going to be just any heat load like we've had in a particular scenario so this one will be a load per unit length and on top of that it's not going to be steady it's going to be a function of time now that we've got this you can obviously interrogate your actual symbolic expression and have your own as well then what we're going to be doing is specify the time step on this and of course the limits and you can have a graphical overview of of what you're inputting day now that we've done this we're now going to be applying a heat on this so let's make it like 30 000. so this is now how you apply a moving load the biggest thing in terms of transient thermal analysis is how you set it up so you have to obviously stipulate that this is transient thermal analysis this is equivalent of your non-linear analysis in your structure then we will specify what we call the initial temperature in the beginning so we will make this to be 30 and on the output it is important that you specify the number of steps you want so i'll i will utilize 101 in my case and you specify user defined in this instance and i know that at the end this is what i would desire and i can say equally space these right so now that you've got this you can save this analysis and run it all right so for the sake of time i already have run this particular study before so here is what i'm going to review how the results look like the same analysis same setup and here's what i'm going to do i'm going to even animate the results so that you get to see the moving load at the bottom there it counts the total number of frames up 201 because that's what i chose and this is what you have as a resultant uh what you call overview so this is how you do a transient thermal analysis showcasing moving loads on an object inside thermal analysis if you've got any questions please don't forget to send those to us don't forget to subscribe like the video until next time good
