time step incompressible flow
I want compute an unsteady incompressible flow expluctly. I gave the courant number but you obtain this message :
"You cannot use global time stepping to compute unsteady incompressible flows"
How to run?

I have a similar problem.
I'm doing a transient, compressible (UDF for density and speed of sound), FSI problem with the use of system coupling. I would like to simulate a pressure wave hitting an object, but i get the same error as the topic creator, even thou my fluid is compressible...help?
Will implicit time formulation, for the explicit density-based solver simulate properly the above mentioned phenomena?
thanks in advance for any help
