Retrieving Topological Information of Implicitly Represented Diffuse Interfaces with Adaptive Finite Element Discretization
Published online by Cambridge University Press: 03 June 2015
Abstract
We consider the finite element based computation of topological quantities of implicitly represented surfaces within a diffuse interface framework. Utilizing an adaptive finite element implementation with effective gradient recovery techniques, we discuss how the Euler number can be accurately computed directly from the nu-merically solved phase field functions or order parameters. Numerical examples and applications to the topological analysis of point clouds are also presented.
