Dear foamers,

I am using many different solver for my simulations and I also use each time different meshing, thus my number of cells varies a lot.

I am wondering if there exists a utility that would do all the hard work of figuring out what decomposition and on how many cores it is optimal to run the sim for a specific solver for a specific mesh?

Thanks

Hi,
Actually not.
Try to scotch to decompose your domain.
Try to stay higher than 40000 cells per processor.

Hi Ardali,

will for sure do that.

Extra question. Is there any way to know how much time (for each time step) the calculation took for each specific cell?

Hi,
That depends on very many things and not easy to use.
For incompressible single phase high quality structured mesh simply divide the wallclock time per time-step to the number of cells.
That is very close to impossible in other cases. Skewness, multiphase, compresiblity and so on matter.
