I solved the same by SIMPLE method, if you are using the same, then the solution will be.. For 2-D problem, then factor 'b' in pressure discratisation equation, which is generaly used for source term should be sufficiently small. for details u should see book by Patankar. For 3-D problem, there is no need for any convergance criteria, just apply four or five iterative TDMA loops over pressure equation(discratised), it will give results. I hope this can be help full. look for other people.. best of luck Happy Lohri
