hello; I'm modeling turbulent mixed convection in periodic horizontal ribbed channel with heat flux at the horizontal face. when I used K-eps model and it's variants the simulation converged; but when I changed the model to K-omega and RSM with the same conditions after a long iterations I obtained a temperature limited.. I don't undrestand why? can any one help me please!! thank you

try to change the underrelaxation factors for pressure and temperature. Use PISO for pressure velocity coupling and PRESTO for pressure discritization . If this doesnt help then you really should run the system unsteady.i hope thid helps
