[snappyHexMesh] SnappyHexMesh cell removal

ali.ghaemi · December 12, 2012, 08:19

Hi

I have a triangulated surface in STL format. SnappyHexMesh generates a mesh outside the surface and removes the cells that are located inside like Fig.5-12 in OpenFoam user guide. However since I need to do the simulation inside I want to retain the cells there and remove the ones outside the surface. I wonder if someone knows how to do that.

Thanks in advance

Hi,

edit your system/snappyHexMeshDict file and modify the following line:

locationInMesh (-1.0 0.0 3.5 );

The location must be where you want to keep the cells.

Regards,
Stephane.
