In the beginning, it quickly converges from nonphysical values to results that I know are OK. But when I leave the simulation running the results seem to 'creep' away from the initially converged results. I tried to increase tolerances in residualControl but it doesn't seem to help. AFAIK, pimpleFoam should run for as any time without trouble, is that right?
