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;
    . . . .
