WebGmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and flexible visualization capabilities. Gmsh is built around four modules ... WebAnother option is to use the program GMSH to define your geometry and the corresponding mesh, and then import this in FEniCS to work with. I have no experience with mshr, but I do believe GMSH will be easier if you need less conventional shapes.
