Hi,

I am setting two periodic boundary conditions in one simulation. These two conditions have difference linear pressure gradient. But Fluent only has one place to set the pressure gradient. I am wondering if you could help me find where to set the pressure gradient for each boundary.

Thank you very much!

It's very difficult to realize the simulation with two periodic boundary conditions by FLUENT. So maybe you can deal with the question through the original defination of periodic boundary conditons.
