is it possible to create Delaunay meshes of 2-d domains with netgen/NGSolve?
I’m using NGSolve to implement time-integration techniques for the time-dependent Navier-Stokes equation in my mater thesis and generally prefer Delaunay meshes, due to the nice properties of the discrete Laplace operator on such triangulations.
Given a set of points you can use scipy to generate a Delaunay-triangulation (see here ).
With that you can create a Netgen mesh manually as described in the documentation .
the meshes at the boundaries which should be periodic have to coincide.
If that’s the case, you can do it the way described in the discussion Christopher pointed you to.
