Error: Divergence detected in AMG solver: species-0 -> Increasing relaxation sweeps
 

All,

I am running Fluent v12 to model the progress of 3 chemical reactions in a packed catalyst bed. I initialized the problem fine, all of my mixture materials, etc are accounted for. But when I start the calculation I get this error:

Error: Divergence detected in AMG solver: species-0 -> Increasing relaxation sweeps!

Has anyone else encountered this issue? I would appreciate the help. This is part of my Ph.D. and I am just getting started on working with Fluent.

Much appreciated,
KS

have you find out the reason of this problem?
