I would like to thank in adavance for reading this It would be helpful if you can suggst me to solve my problem.

Actually I am trying to solve porous model problem (with Isotropic loss model of porosity & using linear and quadratic coefficients) with SST. I have tried with steady state and it was not converging. Then, again I tried with transient also. But I couldn't get the convergence that I set RMS to 10-4. I used almost default settings in the solver part.

I could get the convergence with K Epsilon. But not in the SST even with mesh refinements. FYI.. I have used tetra with prism layers.

Looking forward to hear your suggestions to get the convergence.

Thanks
