SUS Code

SUS code obtains an optimized tetrahedral mesh from a tangled or valid one, by using local node relocation maintaining the initial mesh topology.

This code is an improved implementation (see TechNote.pdf for details) of our simultaneous smoothing and untangling method that is described in the following paper:
