Hello,

Has anyone done any work in figuring out how the number of floating point operations scales with grid point count in any OpenFOAM-based flow solver. I understand that this is a tricky thing because choice of linear solver and setting, etc. will affect the number of FLOPS.

Also has anyone done any work in looking at OpenFOAM scalability on really large amounts of processors, like in the thousands of processorss?

Thank you,

Matt
