steady solver as initial guess for unsteady flow
 

Dear Fluent users

My case is to simulate unsteadiness in a channel. I want to know whether it will be appropriate to run the case using steady state solver to have the initial guess and than solve using the unsteady state.

If your steady-state is not spurious (some problems have no actual steady-state solution), you should be able to start with it.
