Hello,
I'm actually simulating a car intake manifold. I've solved it with constant BC, but I would like to do it with a variable outlet pressure as an engine aspiration.

Is there any function simulating an engine aspiration or something to define a variable output pressure? I guess there is something to do that, I've find things but they didn't clearly solve my needs or explain how to use them.

I'm sorry, I'm new in OpenFOAM and I just know how to use basic solvers

If that helps, I've done the mesh with snappyHexMesh and solved as an incompressible flow (pisoFoam). I just know inlet and outlet pressure (wich is variable), but not velocity, I've solved the initial velocity conditions with potentialFoam

Thank you very much.

regards
