hi all,
I am simulating turbine with air. I wanna present temperature distribution, so I activated ideal gas for density (3D - Transient - Dynamic mesh (6DOF by UDF)
BCs: Inlet: mass flow inlet , outlet: pressure outlet
After a few iteration, the energy residuals diverge!
Any experience or idea can be useful.
regards
