Coupled Solver

Ihab Sraj

Hello,

I'm a graduate student at the American University of Beirut.

I am trying to implement a coupled solver similar to the CFX solver for a course project . The speed up in solution is noticeable as well as the scalability with the refinement of the mesh. However for high reynolds number problem the convergence is very slow due to the convection term dominance.

The use of the false transient term relaxation technique does not solve the problem. I had to under-relax using the old technique and thus the scalability is lost.

I tried using CFX some high reynolds number problems and it seems fine.. What do u think i should do to solve my problem...

I would appreciate your reply, Thanks
