Accordingto your needs you have few options - at least: https://bitbucket.org/benjamik/mshr/ official mesh generator for DOLFIN dev version, check demos in the source tree of the package
External mesh generators like http://www.cs.cmu.edu/~quake/triangle.html http://geuz.org/gmsh/ ... Their output can be converted to DOLFIN format by dolfin-convert script installed with DOLFIN. Refer to their doc and $ man dolfin-convert In DOLFIN 1.4.0 there is CSG (constructive solid geometry) meshing based on CGAL. But this is now deprecated. Refer to CSG demo http://fenicsproject.org/documentation/dolfin/1.4.0/python/demo/documented/csg-2D/python/documentation.html Jan On Thu, 4 Dec 2014 13:28:49 +0000 <[email protected]> wrote: > Good Evening, > > i’ ve a problem i can’t fix.
