Convergence Crieteria for pressure terms in NS eq
Hello everybody
Happy New Year i am solving NS equations and i encountered problems in the convergence of thye pressure terms. what is the best way to converge easy andfast. i am solving both steady and unsteady state equations. Thanks Navdeep 
Re: Convergence Crieteria for pressure terms in N
I solved the same by SIMPLE method, if you are using the same, then the solution will be.. For 2D 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 3D 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
