Gaussian curvature based tangential redistribution of points on evolving surfaces

Abstract

 
There exist two main methods for computing a surface evolution, level-set method and Lagrangian method. Redistribution of points is a crucial element in a Lagrangian approach. In this paper we present a point redistribution that compress quads in the areas with a high Gaussian curvature. Numerical method is presented for a mean curvature  flow of a surface approximated by quads.
