incompressible Mach number
 

Hi everyone!

My apologies if the question is stupid, but how do we get the Mach number in incompressible solvers??

I can only define velocities in the boundary conditions. This would not be a problem if I knew my temperature/speed of sound, but I don't. Is there a default value in simpleFoam/pimpleFoam?

Thank you very much for your help!

Aha, ok I'm stupid. It will not have any impact anyway. As long as my Reynolds number is ok. :)
