Hey,
I have been searching the Net for a couple hours, but didn't find anything about this. So when I use Fluent with the totally same settings but different core settings (Serial/Parallel with 1, 2, 4, 6 or 8 Cores) I never get the same results. Sometimes the residuals converge, diverge or just stay constant. I'm not sure if this is a problem or which settings I should trust. If I use the same core settings the results are also nearly (95%) the same. I have an Core I7 with 4 cores and HT but it doesn't matter. This problem also occur on different PCs with different meshes (last pic with 12 cores). E.g. 1 Core (Serial) ![]() 2 Cores (Parallel) ![]() 4 Cores (Parallel) ![]() 8 Cores (Parallel) ![]() Again with 8 Cores (Parallel) ![]() 12 Cores (Parallel) ![]() Please I need help with this. Maybe someone had an explanation or a solution for this phenomenon... |
