Hi collegues!
Can anybody give my a quick reply on whether GAMG can be used to solve the poisson equation of the transientSimpleDyMFoam solver? (Otherwise I will have to tweak the solver a bit) I didn't manage to get it running so far (with GAMG)... cheers - Michi |

Hi Michi,
the dynamic mesh makes it necessary to disable the cache agglomeration option for AMG. Therefor use the following option in the fvSolution file: Code:
pd { solver GAMG; tolerance 1e-7; cacheAgglomeration off; . . . . |
