I'm sorry I have so many problems,but I'm a new user of OpenFOAM.New I'm solving a steady-state supersonic fluid problem with OpenFOAM.Firstly,I chose the rhoSimpleFoam solver,but it did not work.There are some people saying it isn't suitable to solve supersonic flow.I need someone to recommend me a appropriate solver to solve steady-state compressible supersonic fluid problem.Thank you very much!

Sticking to the manual, there are only '"transient" solvers for supersonic flow, but of course they can be used to solve steady-state problems.
Personally I only use the sonicFoam solver, as it deals with viscid flow. To speed it up a little, I think that is the background of your question, time effort, in many cases for upwind discretization the courant number can be increased (say 10 - 15). Depends on the case. Later one can switch to second order schemes.

Regards

Thank you for your reply!I used the sonicTurbFoam solver to solve my problem ,it worked well.However,it cost a lot of time to get a convergence solution for the cells were small.Can you recommend a solver which can get the right result more quickly.Many thanks to you!
