Hi!

I would like to enforce a average flow pressure in an outlet. Say 100kpa average flow pressure. that's why I would like to use average pressure. So what boundary condition should I use?

I think that I CAN NOT use, fixedValue pressure and Zero-gradient velocity.

Thanks.

Do mean something like fixedMean?
