Hello Foamers,
I have a problem: during the simulation the temperature start rising unexpectly and the simulation is diverging. In my simulation I would cover some air space (1x1x1) and solid rod crosing air volume (0.1x0.1x1) in the center of the XY face. The flow should be buoyancy-driven without external momentum sources. What's the source of the divergence? Files in attahment.
