Thanks a lot!

I see that I should have changed all the related p_rgh to 1e5, especially the surrounding fixedFluxPressure, not just the internalField and the outlet.

Cheers! Please let me know if you need any help in the future. Gonna test the more difficult scenarios.

I am facing the same problem of above. I am running a CFD simulation in OpenFOAM (v10) of a compressor, working fluid perfect gas. The solver is rhoSimpleFOAM, MRF approach, omega = 1500 rad/s , the pressure and velocity fields are correctly simulated, while the Temperure does not increase as it should, it remains almost constant.

could you kindly give me a hand?
