I am trying to run simulations in OpenFOAM (2.3) on air-bearings.

In the past I did simulations to see the transient effects on air-bearings with "sonicFoam"-solver.

It was often unstable (leading to crashes too), mostly because I only know the inlet pressure (6 bar) and the outlet pressure (1 bar) and I understood solving a pressure-pressure system is hard work.


However, nowadays I need to do simulations in order to get the steady-state solution of air-bearings, and not the transient situations. Essentially we want to know the pressure p in every cell inside the mesh to perform calculations based on that.

I can imagine a steady-state solver would be faster than a transient-solver as sonicFoam. And perhaps more stable too...


What solver do you recommend? and why ? If necessary, I can give you a copy of my current case folder so you can see the mesh and setup.
