Multigrid error on 2D Eurelian flow

Hi,
I am studing a two phase flow (air and water) inside a reactor, and I am modeling a 2D slice of these reactor with FLUENT 6.2.16 under Windows 2000. Am facing problems with the stability of the results, with divergence sometimes. I think the problem is the multigrid settings. If I set all the AMG methods to "selective", the results for the flow get better, but the energy not. I get the message "Restrict_Defect: Using stored RESIDUAL" when I set the Verbosity of the AMG solver to 2. Have anyone faced this kind of problem? Thanks, galeazzo |
