Hello,

As Yvan mentioned, you can change the time step factor (cdtvar) for the temperature to have similar characteristics times to reach a steady solution in case it exists.

In the following figure, you can see the difference in the temperature field for the same simulation time, while the velocity is the same.

Hello, could you share the example with the mesh and everything?

Hello,

To have rough wall option, you have to set a turbulence model and also a wall function, for default no wall function is used, soy the rough wall option is in gray.

But I have no option rough wall even if I tick turbulence.

Attached is the case (The mesh correspond to the first post and should be improved). Regards,
