nodes )) print ( ' % d Elements' % len ( self. The resulting new ParaView plugin named GmshReader is now provided with the official ParaView source code (version 5.7.0 and above). Yes, you can store a vtkUnstructuredGrid (which can be used to represent a 3D mesh) into a vtu file. Note that contrary to Gmsh, VTK supports exclusively Lagrange polynomials and ParaView provides uniform h-refinement to visualize these polynomials. elements = ( etype, tags, ) print ( ' % d Nodes' % len ( self. So far the only format that I can see that exports the boundary > condition/surface names is your own msh format, having looked in the > ascii vtk file it does not contain these names. You may look at CGAL ( or a python wrapper of CGAL ), Gmsh (or a python wrapper of Gmsh) or TetGen (or PyVista Wrapper of TetGen) for more general mesh generation capabilities.

This is heavily based on the original Gmsh.py by Carl Osterwisch.

There, you are able to generate the surface mesh by clicking on Mesh->Define->2D, however, for Mesh->Define->3D there is no result, right One thing that this could indicate is, that your geometry does not specify a volume, only surfaces. To install or upgrade gmsh: pip install -upgrade gmsh After installation you can either run the Gmsh app: gmsh or use the Gmsh Python API: python -c 'import gmsh gmsh.initialize () () gmsh.finalize ()' (Note that the header files for using the C++ and C API are also installed, as is the Julia module.
