Hi,

I need to simulate a rotor. because of the speed of the fluid (0,4<Ma<1,3), it's necessary to use the physics "high mach number flow". In that case, Comsol seems to offer just the turbulenz model k-epsilon.
But it's necessary to use k-omega to get a good result.

Is it possible to implement it? Has anyone done it yet and has a pattern or sample for me?

Thank you!

Paul

I am using Version 4.3.
