Boussinesq model applies when you set a reference temperature in the fluid domain. Transient simulations still use the Boussinesq approximation. Nothing changes if you do steady state or transient:...

Don't get me wrong, automatic time scales are fine to begin with. However automatic time scales is just a guess, CFX is trying to predict the...

CFX uses physical "false" timesteps for solution control in steady state simulations. In CFX pre check to see that you have physical timesteps enabled and not automatic timesteps. It should be under...

In general for solid fluid heat transfer you need to understand physical time scales to aid better convergence. For example calculate the...
