Default constant pressure gradient
Posts: n/a
I have some analytical solutions I want to compare with Fluent solutions. The first case is a simple channel with mass flow inlet and outflow outlet. How do I specify a constant pressure gradient through the channel for this case?

You cannot specify both mass flow and pressure gradient, too many boundary conditions. You can only specify one or the other.

Are you guys trying to simulate fully developed flow?
