divergence detected in AMG solver !!!

yansheng

Hello friends,

i have a question, hope somebody can help me out ? when i run the simulation in fluent ? after few thousend iteration, i got the message:

divergence detected in AMG-Solver: pressure correction !!!

i have read also some message about this problem in forum, but none of them explain the reason, why the divergence occur ? can somebody explain me, what is the AMG-Solver ? if i continue the simulation, (that's mean fluent will automatically change the pressure) ? Question: will i get the wrong result later ? or how far will the result deviate from the exact result (without pressure correction) ? i think this could be interesting for all of us. ^_^

hope somebody can help
