I am starting with cfdof with very simple test case and I can't get it working.
It is cube 1m edge length, with air in it, and different walls temperatures.
I am interested in natural convection.
Even with simplest settings and defaults it doesn't solve, crashes after few iterations.
Steady as well as transient.
Is there something essential ignore?
I see, all this is complex, and I have to learn, but e.g. :
- why in physics model Task-GUI, if I set "incompressible" the gravity is grayed? (for natural convection in water).
Thanks in advance.
I use FC 0.19 AppImage on WSL2

Re: simple example fails
Your case runs without crashing for me. If you include your full output it may give a clue as to what is going wrong.rentier wrote: ↑Sat May 08, 2021 11:01 am I am starting with cfdof with very simple test case and I can't get it working.

This is because the incompressible solver doesn't support buoyancy. The compressible one can be used instead.I see, all this is complex, and I have to learn, but e.g. :

Thanks a lot!
Attached the case folder with logs, the voluminous mesh deleted.

Re: simple example fails
Ok, thanks for your time and your interest in helping. Anyway, I will try and play around for some time with cfdof and possibly learn something.
