Greetings Dark lancer,

Those are somewhat two different topics, because:

The STL is probably the geometry for which you want to create a mesh. In OpenFOAM, the usual way to generate a mesh with STL as the geometry, is to use snappyHexMesh: http://openfoamwiki.net/index.php/SnappyHexMesh
For DSMC, check the tutorials available in "discreteMethods/dsmcFoam".

If you are still unfamiliar with how OpenFOAM works and where the tutorials are, then read the OpenFOAM User Guide: http://www.openfoam.org/docs/user/

Best regards,
Bruno

thanks wyldckat
ok
I am reading user guide but I found an Instructions and I follow them
after I save my file with(.stl) I use NETGEN softwar for generating mesh and save with (.vol) and now I don't know what I do with these files?

Hi,
so you want to take the netgenNeutralToFoam way http://openfoamwiki.net/index.php/NetgenNeutralToFoam (remark:foamX does not exist any more [used to be a Java GUI with few capabilaties])
in this forum =>http://www.cfd-online.com/Forums/ope...-openfoam.html

But Bruno is correct from STL it is a good way to use SnappyHexMesh(SHM) and I would use Helyx OS as a GUI to tackle SHM.
