Pygmsh example. I followed the example described here , which deals with the electrostatic potential of a sphere-sphere capacitor. The example works very well! So far so good. Now, I want to create my personal 3D capacitor (a 3D sphere in front of a plane) with the help of pygmsh and got stuck in the description of the boundary conditions.

I am using pygmsh to create a mesh and save it using mesh.write('mesh.geo_unrolled). I use a nested for loop for the creation of my geometry which is a half channel with a cube at the bottom wall. I take user input for a bunch of parameters and the output is nx and nz number of cubes in x and z direction respectively and a half channel around it.

You have so many tutorials I don’t know which one to refer to - and most recent ones are for FEniCSx. Using pygmsh and meshio is also very new for me, I am really struggling. The 3D mesh tutorial in your page is confusing for me right now if that is the one you refer to. I couldn’t find an example or tutorial on how to mark using integers.Bases: pygmsh.common.geometry.CommonGeometry. Add circle in the x - y -plane. Creates an ellipsoid with radii around a given midpoint x 0. Embed the point (s) or curve (s) in the given surface. The surface mesh will conform to the mesh of the point (s) or curves (s).Examples of other packages which work with unstructured meshes are listed below. See also this list for many other mesh generation tools. pygmsh. The pygmsh Python package provides useful abstractions from Gmsh's own Python interface so you can create complex geometries more easily. It also provides tools for 3D operations (e.g. extrusions).

pip install pygmsh --user. 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.

Back in #331, I learned how to set the fineness of the mesh using extra_gmsh_arguments, but this seems to have gone away in v7. How should this be done with the new API? I'm looking to pass arguments to gmsh such as clscale and clcurv.
