Hi everyone,
i am trying to write SIMPLE scheme for solving Backward facing step problem in fortran 90. Using Finite volume with QUICK, I can solve until iteration 100, but after that my simulation seem diverge. I know this problem usually caused by inaccurate boundary condition. However, I re-check several time the BC is fine. It will be great if someone here can give me solution. I attached my ugly code here.

Thank you
Gugum
