Hi,
I have currently built a 3D geological model using Leapfrog Geo 5.0. I aim to create an unstructured 3D mesh in Feflow using the GM exported from Leapfrog (*.lfm), which consists of 6 volumes corresponding to the 6 diferent lithologies.
When I try to generate the unstructured mesh using "Supermesh import from maps", if I import the complete model (as 6 volumes-contact surfaces) , I get the following error from TetGen: "[b]Tetgen meshing error: A self intersection was detected[/b]". If I import just one of the volumes (from a separate *.lfm file) the error disappears and my unstructured mesh is generated, obviously just for the volume that I have imported.
How can I adress it in order to generate a mesh for all my domain, including the 6 lithologies?
Also, once the mesh is generated, is there an easy way to select the elements that correspond to one lithology? I am thinking of groups of elements in the selection panel generated automatically from de *.lfm input file.
Thank you,
Guillem
