pressure gradient in fluent

miniar · November 13, 2012, 08:44

hello! please i want to plot with fluent the gradient pressure dp/dy in channal (incompressible fluid,unsteady velocity), the profile of velocity was correctly ploted but the gradient pressure doesn't have the periodic profile.

I have seen this before. Fluent separates the pressure into a linearly varying (constant gradient) part and a periodic part. I don't use Fluent enough to tell you how to combine them but there is a way. Search around for this or try the Fluent forum.
