Hello everyone,
For a school assignment I came across this method to analyse the effect of our groups chosen insulation. After doing the tutorial and some calculating to be able to fill in all the blanks asked, the simulation gave me a warning which I was not able to fully read. It seems to be related to faces and frankly I do not know how to solve it since my skills regarding this program are still somewhat lacking.
Does anyone know how to solve this issue. Or able to tell me what I am doing wrong. My goal with this simulation is to see how if the temperature decrease required in our assignment is theoretically possible. Thus we need the temperature on the top of the pad

Hi @ybuurman!
I had a look in to your analysis case. I also tried to perform a quick analysis over it. But I did some changes also. I created a manual mesh such that I have mesh consistency between the contact regions. This is done to have a proper conduction between the two solids.
Your contact definition was also not defined properly. The contact has to be between the two contacting surfaces. Moreover, the warning you were receiving was telling you that you have defined multiple boundary conditions i.e. surface heat flux and temperature on same surfaces. This is just a warning telling you that you might receive odd results due to this. So in general either you can define surface heat flux or a fixed temperature.
As an additional analysis, I took a quarter model since it is symmetric and created a mesh such that I have at least 2 elements over the thickness of the thinnest solid. Similar analysis was performed for that case also.
You can have a look at the project here: SimScale
In case of any question/s, feel free to ask.
Best,
Ahmed
