cfx12 x64 meshing: pc has 4 core but only 1 core working for the mesh? why?

previously, cfx11, when meshing on 32bit with dual cpu, both 2 cpu working HARD on the mesh....

why 64bit with CFX12 cannot mesh parallel ?

thanks for advices !

Hello everybody!

I'm probably too late, but here is a tip if not tried yet. While in cfx-mesh use the outline:
Options->Volume Meshing->Parallel Advancing Front, then set the appropriate number of partitions. Done successfully on 4 different machines, both 32 and 64-bit.

Hope, I've been helpful.

PS That doesn't work with Extruded 2D Mesh.
