I'm trying to construct a rectangular grid with features at arbitrary
locations. The most straightforward way of doing this that I can think
of is to generate a rectangular hypercube, delete the
cells/edges/vertices around feature locations, and then attach other
triangulations (e.g. a hyper_cube_with_cylindrical_hole) at the vacant
locations.
Is there a simple-ish utility for removing parts of the domain in this
way? And does the process differ for a distributed triangulation? I've
been perusing the documentation for Triangulation, GridTools, and
GridGenerator and haven't been able to find anything.
There are functions in namespace GridGenerator that (i) create a mesh
from another one by removing individual cells, and (ii) create a mesh
from two or more other ones by merging them. I forgot the name of the
former, the latter is called GridGenerator::merge_triangulation().
