Error: divergence detected in AMG solver: pressure correction
 
Hi,
I am trying to do turbo-machinery simulation in Fluent 6. I generated mesh using ICEM, it is havnig periodic boundary condition.

During grid check in fluent, it shows no error. But after initializing when i click for ' iterate ', I get following error.

Error: divergence detected in AMG solver: pressure correction

What should I do ? Please help :(

Regards Sabin Mathew

Please try to lower the under-relaxation factors of pressure.
