isothermal solution of chtMultiRegionFoam
1 Attachment(s)
Hi,
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. Any idea? Attached image is the T field at the end of the solution. Thanks, pilafa |
hello,
have you tried a more densed mesh? or a low maximum Courant number (/lower timestep)? ciao |
