Gmsh is a powerful mesh generation tool with a scripting language that is notoriously hard to write. The goal of pygmsh is to combine the power of Gmsh with the versatility of Python and to provide useful abstractions from the Gmsh scripting language so you can create complex geometries more easily. See here for the full documentation.Python Examples¶. Please see this page to learn how to setup your environment to use VTK in Python.. It would be appreciated if there are any Python VTK experts who could convert any of the c++ examples to Python!. VTK Classes Summary¶. This Python script, SelectExamples, will let you select examples based on a VTK Class and language.It requires Python 3.7 or later.{"payload":{"allShortcutsEnabled":false,"fileTree":{"examples/other":{"items":[{"name":"dolfin","path":"examples/other/dolfin","contentType":"directory"},{"name ...To clarify, I don’t generate or read any msh-files directly, I run the pygmsh command: msh = pygmsh.generate_mesh(geom) which returns an “msh” object. I don’t know if that is the same thing as reading an msh-file generated by gmsh (pygmsh generates temporary .geo->.msh files, in /tmp, but the user never see them).

The final step is to create the mesh from the topology and geometry (one mesh on each process). mesh = create_mesh(MPI.COMM_SELF, cells, x, ufl_domain) As the meshes can contain markers for the cells or any sub entity, the next snippets show how to extract this info to GMSH into dolfinx.MeshTags.FWIW you may check Joachim Schoeberl's NetGen/NGSolve and the examples therein. It can import geometries from several CAD formats and then export to Gmsh/Abaqus format following which you can use meshio to convert these to xdmf to be imported in dolfin. (looks a bit tedious than simple Gmsh/pygmsh->meshio route but it isn't)It also provides close integration with the pygmsh package (Schlömer 2018), which is a powerful Python tool for mesh generation. For example, the user can quickly generate a grid adapter, to refine a rectangular grid in a given domain by: ... Other examples utilizing pygmsh can be found in the package documentation. Figure 3.For example, the following command extrudes the surface 11 // along the z axis and automatically creates a new volume (as well as all the // needed points, curves and surfaces): Extrude {0, 0, 0.12} { Surface{my_new_surfs[1]}; } // The following command permits to manually assign a mesh size to some of the // new points: MeshSize {103, 105, 109 ...
