buoyantSimpleFoam crashes at Time 2
1 Attachment(s)
Hi all,
I am currently stuck on the same issue for a long time. I have used the circuitBoardColling as an initial template to solve a simple heat transfer problem where I have an inlet and outlet flow and a box in the middle generating heat at a constant temperature. However, the solving always crashes at time=2:

Does anyone have an insight on what could be causing this crash? I was guessing it could be boundary conditions. You can find the folder to run attached.
