get instationary response
work on a flow around an airbrake, which in reality has transient solutions. The problem is that cfx always send me the same steady response, even when I lauch the transient mode.
How could I do to get a transient solution, how could I insert the instationarity? are there typical initial conditions, typical boundary conditions to get that kind of transient response?
Thanks for your help
some things that come into my mind:
Is the mesh fine enough?
Did you try different turbulence-models?
Is the timestep fine enough when performing an instationary solution?
Are the flow velocity and the fluid parameters compareable to reality?
