SIMPLE based FVM lid driven cavity convergence problem

akin · June 16, 2012, 07:55

I have been writing a Matlab code for the lid driven cavity for quite some time and I can't find convergence. I want to know how to implement a segregated solver for this problem using gauss Seidel. Can someone help me with a step by step Procedure of solving the u,v and pressure correction equations with segregated approach and under relaxation techniques.

Which algorithm did you use to resolve the pressure velocity coupling. SIMPLE?
I think you can find the step by step procedure of SIMPLE in PANTAKAR'b book<numerical heat transfer and fluid flow>.
the general procedure of SIMPLE algorithm on staggered system are as follows:

Solve U
Solve V
Solve Pressure Correction
Correct U V and P

repeat the steps until convergence.
Also, in my blog , there is a fortran 90 version SIMPLEC algortihm 2D.
