Maybe he can share those?
This should be possible. It is a c++/python wrapper around Triangel <http://www.cs.cmu.edu/~quake/triangle.html>, for 2D meshes and as allready mentioned tetgen for 3D meshes, called TriTetMesh. It saves meshes in the format possible from these two libraries, in addition to dolfin. You are also able to set markers to vertices, segments and, triangles for 2D and, in addition to these also for tetrahedrons in 3D. This information is then written to appropriate Meshfunciton files. I will just give the code some final love and then I can share it. Thanks to Anders for good comments on the usability :) Cheers, Johan _______________________________________________ DOLFIN-dev mailing list [email protected] http://www.fenics.org/mailman/listinfo/dolfin-dev
