The SIMPLE algorithm is not too simple for me
2 Attachment(s)
Hi,
I try to simulate the gas flowing through a tube filled with spherical particles in the steadystate regime. The equations are solved using the finite volume method and I try to implement the SIMPLE algorithm to get the correct pressure and velocity fields that satisfy both continuity and momentum equations. I tried for a week to solve the problem but I didn't manage to do it correctly.(I got negative velocities at some nodes :cool:) I will be happy if some one can give me a clue on how to solve the problem. You will find a detailed description of the procedure I adopted in the pdf file attached to this post. Thank you in advance, Zeke.

Hi Ztdep,
I will try to understand the global fortran code. Thank you for your help and have a nice day, Zeke.
