Joe Guest Posts: n/a	Hi, I have to do an unsteady CFD on an airplane propeller in front of a non-symmetric fuselage (sliding mesh). Does anyone know, with what kind of steady solution I should start the computation? The problem is unsteady by definition, so there is no real steady solution to start with, is there? How should such an unsteady computation be started without having to accelerate all the way from zero velocity? Thanks, Joe
