This is an example showing how to create a mesh of a simple skrew using the built-in geometry module: To create the above mesh, simply do: …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.

Note that with pygmsh, boundaries with the same tag has to be added simultaneously. In this example this means that we have to add the top and bottom wall in one function call.I tried to replicate the circle diffusion example as follows.

In Gmsh, with the default built-in factor, this is provided by Spline rather than BSpline; however, pygmsh/built_in currently only provides the latter. As the .geo syntax is identical, this should be a straightforward addition.
