Efficient Treatment of Complicated Geometries and Moving Interfaces for CFD Problems

The efficient representation and handling of complicated geometries is one of the main challenges of today’s numerical simulation. In the area of computational fluid dynamics, e.g., geometry plays a more and more predominant part. Especially for problems with moving interfaces, when we think of the cost of a successive remeshing in a finite element context, e. g., those geometric aspects seem to be at least as important as the construction of appropriate discretization schemes and solvers.
