I am a masters student at TU-Delft, doing my thesis now on Immersed Boundary Method and its application to deformable body.
I use a Volume of Solid immersed boundary method that requires to compute the volumes(areas in 2D) intersected by my control volumes (grid cells) and the polygon,(immersed boundary). Through NOTUS, I have found how to do this in 2D through boolean operations on polygons.(It has a tool from computational geometry that allows me to do this ). I am a little confused on how should i be implementing this in 3D. I searched through the NOTUS documentation for a tool, that gives a polyhedron from the intersection of one polyhedron and another, but i did not find it.
I scanned through the Notus documentation for Computational Geometry tools in 3D, and could not find this. There are routines for line/polyhedron intersection, polyhedron flooding , but none for intersection of polyhedrons. Can someone guide me ?
