Implement half-edge mesh #70

Open KyleVaughn opened 1 year ago

KyleVaughn commented 1 year ago

It is unclear whether a HalfEdgeMesh will be more or less performant than a FaceVertexMesh for neutron transport. We should implement the HalfEdgeMesh and benchmark.

To determine if there is a potential benefit, we could run a few simulations in MPACT, keeping track of the number of mesh.intersect(Ray) tests and mesh.findFace(Point) tests in UM2. Then, benchmark both functions for FaceVertexMesh and HalfEdgeMesh and perform a bit of arithmetic to determine the projected performance.

Consider the performance on a pin mesh and on a larger mesh, since it is sometimes necessary to simulate a fairly large mesh as a "single pin".
