Dear all,

I am using Patankar's SIMPLE algorithm for velocity pressure coupling in a turbulent pipe flow. When I calculate pressure values for correcting velocities, I find pressure values that are bigger in an order of magnitude than normally anticipated pressure values. This is my code.

However, in fluent for instance, pressure relaxiation for SIMPLE is about 0.3 fixed value.

I would like to share my formulation and codes etc, so a personal contact would be much appreciated.
