Titel:
Interface handling for three-dimensional higher-order XFEM-computations in fluid-structure interaction 
Abstract:
Three-dimensional higher-order eXtended finite element method (XFEM) - computations still pose challenging computational geometry problems especially for moving interfaces. This paper provides a method for the localization of a higher-order interface finite element (FE) mesh in an underlying three-dimensional higher-order FE mesh. Additionally, it demonstrates, how a subtetrahedralization of an intersected element can be obtained, which preserves the possibly curved interface and allows therefor...    »
