EDD1E is on a distinguished road
Hi everyone,

I am simulating a gas turbine stator passage and I have some Problems with the convergence. I set a Monitor Points behind my Blade near to the Shroud for Pressure and Temperature. While the Monitor Point for Pressure is not changing, the Monitor Points for Temperatur is Oscillating.
The RMS Residuals are between 10^-4 and 10^-5.

The flow is compressible, so that I am using the Total Energy Modell with Air Ideal Gas. At the Inlet I set a Total Pressure and at the Outlet a Static Pressure.

Does anyone habe any suggestions?

Tim

Opaque will become famous soon enough
Would you mind posting plots for the convergence of MassMomentun and Heat Transfer?

You can also create an additional plot for the Imbalances showing for P-Mass, H-Energy and U/V/W-Mom
