isothermal solution of chtMultiRegionFoam
I am running a simple 2D problem with chtMultiRegionFoam. On the bottom of the domain, I have a thiner solid region. On top, a air region with air flowing on the solid.
First, I would like to test the isothermal problem. I set ALL my boundary conditions to: T=300.
On the postproc, I checked that at time=0 I have everything at T=300.
But during the solution, the temperature in the fluid domain raises!
I don't know where this heat comes from since I have everything at the same temperature.
Attached image is the T field at the end of the solution.
have you tried a more densed mesh? or a low maximum Courant number (/lower timestep)?
