Hi,

In my problem, I have a jet flow from body with high temperautre, so I need to use this rhoSimplefoam compressible solver. My freestream velocity is about 20m/s.

When I start rhoSimpleFoam, it is crashed at first step when solving p. I tried to switched off temperature jet flow by make temperature same with interior temperature and massflowrate to 0. It is still crashed at first step with same issue.

Could anyone suggest if there is a way to make it work or if there is anythong could wrong?

Thanks very much.

Thanks very much for your reply. I found what is wrong. My rho relaxation factor somehow disappear from fvSolution, so P is blow up.
