Hi all,
I was wondering if there's any solver in the Openfoam framework that is suited for transonic flows where Mach number is 0.95-1.3;
I have tried rhoSimpleFoam with transonic option but it proved to be unreliable and often unexplainably crash.


Running transient solvers is not an option as I do not have to computational power required for my problem.
I'm simulating an aircraft that's 10m in length and the computational domain is 100m in each direction.

Hi,

many factors influence stability - it's difficult to help without information:

What's your case setup? fvSchemes, fvSolution

What kind of mesh do you use?

Do you have any idea of the mesh quality?

What's the mesh size?

What hardware do you use: CPU, GPU, RAM?
