Immersed subdomains

[krober10nd]

• Support for domain embedding i.e., 3d geometry embedded within a larger 3d geometry (ball inside of a ball, etc.)

• Define a new geometry signed distance class Embed which has an additional field called label. At initialization of the points for generation, points are given an integer label depending on which SDF they belong in.

• During mesh generation each SDF of the domain is evaluated but the point can only return back to its initial domain where it was seeded.

present an implicit function that could be used for meshing immersed subdomains.

Turns out you can simply loop over a set of distance functions inside the mesh generation loop when performing the project points back into the domain step....pr soon.
