Hi,

I am trying to simulate a ceiling fan in a room with a steady state flow. There is two domains, one rotating (the fan enclosed in a cylinder) then a stationary domain enclosing the whole ceiling fan as a room (box). There is an exhaust and then also the mesh is good quality in all critical areas necessary.

I also tried different values of the timestep (physical) both starting small and big to then continue with a smaller/bigger step. I also have the air at 25C and tried the simulation in laminar flow too.

My simulation goes down to about 1.e-035 and then goes back up.

I also tried the approach of mesh size/omega or velocity of the flow.

Kind regards,

Hi Michelle,

did u manage to solve this issue?
