Pre-Processing for Large Models
 
I simulate the cooling of an lectrical drive and I use the Ansys Company Products.
I generate the mesh for one wedge (one rotor pole) with around 1.2 Milion cells, after that I rotate the original wedge fiteen times in order to have a Model for a Quarter of a Mashine with 18 Milions but at that moment CFX-pre get so slow that I need to try other Programs. For example if I close CFX-pre, it takes around two hours for CFX-pre with my new PC to be opened again.
How fast would FoamX work with a 16 Milion Cells Model (12 Milion Hexahedre and 4 Milion Tetrahedre). ?

Hello,

FoamX (used to be a java based Gui for OpenFOAM), but FoamX is not supported anymore (ended with OF1.5). http://www.cfd-online.com/Forums/ope...oam-1-6-a.html

OpenFoam is not to strong in the in the preprocessing area, exept SnappyHexMesh (SHM)
http://www.openfoam.com/archive/1.7....ppyHexMesh.php
therefore converters help in preprocessing area
http://www.openfoam.com/features/mes...meshConversion fluent->Openfoam
or Openfoam -> StarCD/Fluent or CGNS
