Pygmsh example
It provides useful abstractions from Gmsh's own Python interface so you can create complex geometries more easily. To use, install Gmsh itself and pygmsh from pypi: [sudo] apt install python3-gmsh. pip install pygmsh. This document and the tests/ directory contain many small examples.

Current Approach: I am currently parsing the .poly, .node, and .ele files generated by Triangle into a python dictionary. Then, using pygmsh and meshio, I am creating a ...Welcome to pygmsh's documentation! ... Elementary geometrical entities can then be manipulated in various ways, for example using the Translate, Rotate, Scale or Symmetry commands. They can be deleted with the Delete command, provided that no higher-dimension entity references them. Zero or negative identification numbers are reserved by the ...For example (in legacy fenics) sphere: sphere = Sphere(Point(1, 2, 3), 5) mesh = generate_mesh(sphere, 32) ... To create simple meshes I would suggest using Gmsh or pygmsh. Both of these modules uses the gmsh.model which can be directly converted into a DOLFINx mesh using dolfinx.io.gmshio.model_to_mesh;

and a corresponding file.msh. As far as I understand, nowadays, it is preferred to use pygmsh, but I'm not sure how to reproduce the very same file.msh. Now, the next step is to use FEniCSx on the file.msh. My attempt is the following: import meshio # 1: sample volume # surfaces # 5 left end # 6 right end msh = meshio.read("file.msh")Here are the examples of the python api pygmsh.Geometry taken from open source projects.

Dear all. Already for some time, I use FEniCS in a docker environment + gmsh + pygmsh + meshio. Here are the specifications of my system: Lubuntu 18.04 FEniCS docker version 2019.1.0 Inside the FEniCS container, I installed the packages as follows: sudo apt update ; sudo apt dist-upgrade sudo apt install gmsh python3-h5py …the conformity of the mesh when, for example, two surfaces share a common line.

The mesh can also be generated from scratch directly in Gmsh either using its GUI and/or its internal scripting language. Note that toughio is not required at this preliminary stage of the pre-processing. This example only intends to show how the mesh used in this sample problem has been generated.
