Hello Foamers,

I have a multi-species, compressible fluid, steady-state problem. The solver I can choose is reactingFoam. This is a density-based, multi-species, compressible fluid, transient solver. But I can set it up as a quasi-steady-state solver.

It didn't run well: diverge for steady-state computation. If I run it using transient solver and run it for a long time in the hope to reach steady state, it gives a good results but it takes extremely long time ( 4 days on 32 cores computer).

I ran the same problem using Ansys Fluet pressure based solver, it completes quite quick in 1 hour.

I'm wondering if OpenFOAM has a pressure-based compressible fluid solver developed. Thanks in advance.
