[Gmsh] Working with other constructive solid geometry backends?

[Gavin Ridley]

Hi all,

I'm curious approximately how much effort would be required for creating
meshes in gmsh using other constructive solid geometry engines aside from
OpenCASCADE. It's typical for Monte Carlo radiation transport programs to
have built-in CSG which provides functions to calculate distance to nearest
cells, what geometry cell a point is in, etc.

What kind of functions are required for gmsh to program something like
this? Is an idea like this even remotely feasible? It would be incredibly
convenient for nuclear reactor assembly design work. An example of a
program like this is OpenMC.

Gavin Ridley
