Hi all,

I'm planning to use OpenFOAM to analyze the following physics:
flow in porous zone, probably with rotating mesh (fans), conjugate heat transfer, radiation and combustion.

I will deal with a computational domain with 10-20 millions of cells, approximately.

As workstation, my intention is to have a total amount of number 2 intel XEON processor with 128GbRAM.

What I would like to know is:
is it better to have two processor with less total number of cores(8), but higher frequency(3.5GHz)? Or to have a lower frequency rate (2.2Ghz) but higher number of cores (20)?

I know that it sounds like:"bird in the hand might be worth two in the bush", but if some user can share his/her experienxe, it will be of help.

Thanks.

Regards.

Michele
