compressible flow
 
im working on a simulation of axial compressor passage, and im having problems using the compressible flow.

which are the caracteristics i have to use in problems with moving frames if a want to use compressible flow?

i tried with segregated model, because fluent recomend this, and k-epsilon turbulence, because it has a small mach number, but neither of those are used in the tutorial of compressible flow. i also put the velocity formulation relative, and if i used the coupled model i canŽt do this, and fluent recomend this velocity formution.

when i did my first iteration it gave an error with the flowting point, i i check the mesh and itŽs ok, then i tried it whitouth the compressible flow and it run.

i donŽt know if the operative pressure may be an issue, iŽm using the default one.

i also check all the boundary conditions with moving frames and the problem presented when i treid to do it whit wall speed

i donŽt know what im doing wrong

thank in advance
