Ccx on linux computational timing

1

hello everyone,
currently what is the best way to run cxx on linux in terms of computational timing for big model?
Thank you

For mechanical analysis; First, reduce the size of your model as much as possible. Use second order elements, preferably 20-node brick elements or 10-node tet elements. You will generally need less elements for a decent answer compared to first order elements.

Incompatible mode eight-node brick elements (C3D8I) are pretty good at capturing displacement, but the stresses can be way off.

Lots of RAM.
Multicore CPU (although IIRC the gains above 4 cores are limited).
PaStiX solver.
