Title:An Accurate and Robust Finite Element Level Set Redistancing Method
Authors:Patrick Esser, Jörg Grande
A new redistancing method for piecewise polynomial finite element level set functions is introduced. The method directly computes the distance to the implicitly given discrete level set. Rigorous error bounds and numerical experiments are provided. Both show that, up to constants, the method is as good as the nodal interpolation of the computationally unavailable signed distance function of the continuous level set.
Keywords:level set method, redistancing, reinitialization
