franzisko is on a distinguished road
hello,
I performed a simulation using simpleFoam and for different parallelization strategies: number of processors, simple/hierarchical/... I get slightly different results. Is there anyone which knows it is ok, or if there is any problem. The difference seems to be small (more or less 1% on drag coefficient for the stationary solution). Where is the part depending on the decomposition method?

thanks a lot,
Francesco
