Hi:

Is there any way I can set fixed pressure gradient value at channel cyclic inlet boundary? I am using channelOodles solver now. The problem is when I set a constant velocity at inlet,similar to sample case channel395, it is really hard to get converged even if I put a perturbation in the initial velocity field. So I am wondering if I can put a fixed pressure gradient at inlet, just like what Fluent periodic condition does. Thank you.
