Titel:
An XFEM based embedding mesh technique for incompressible viscous flows 
Abstract:
This paper presents a finite element embedding mesh technique to efficiently embed arbitrary fluid mesh patches into Cartesian or unstructured background fluid grids. Our motivating application for such a technique is to efficiently resolve flow features like boundary layers around structures, which is achieved by attaching fluid boundary layer meshes around these structure surfaces. The proposed technique can be classified as a nonoverlapping domain decomposition method. The particular...    »
