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:

"Simultaneous untangling and smoothing of tetrahedral meshes,Computer Methods in Applied Mechanics
and Engineering, 192 (25) 2775--2787 (2003)."
SUS code obtains an optimized tetrahedral mesh from a tangled or valid one, by using local node relocation maintaining the initial mesh topology.

If you use this code in a research work, we would be grateful if you cite the above paper.
