ADAPTIVE LEVEL SET METHOD BASED ON GEOMETRIC CONSERVATION LAW

A new method for moving mesh formulated besed on level set functions, which are solutions of the standard level set evolution equation with Cartesian coordinates as initial values, The intersection of level sets of the evolving functions from a new grid each time. The velocity vector in the evolution equation is chosen according to Geometric Conservation Low (GCL) method.
