I have a tet mesh - 800,000 cells - that I want to run steady-state compressible. The mesh is too coarse to capture any boundary layer effects, but in Fluent I have run it viscous as it seems to help with convergence.

I have got as far as converting the mesh and playing with boundary conditions in FoamX, but not really understanding what I'm doing even after trying the tutorials.

The mesh is a jet aircraft engine intake in a freestream. In Fluent I would set pressure inlets and outlets for the farfield, and a pressure outlet for the engine face. I would calculate the static pressures from compressible flow functions.

As a complete newbie I'm at a bit of a loss where to start with Foam, even down to not being sure which solver to use. Any patient hints would be gratefully received!

Once I have a solution I then want to perform a lagrangian calculation of water droplets impinging on the inlet, so anything I can do to that would make this easier (or possible) woud also beof interest.

Many thanks in advance
