temperature limited
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

Re: temperature limited
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
let me know ,hows the solution |
