High order unfitted finite element methods on level set domains using isoparametric mappings
Christoph Lehrenfeld
We introduce a new class of unfitted finite element methods with high order accurate numerical integration over curved surfaces and volumes which are only implicitly defined by lev…

High order exactly divergence-free Hybrid Discontinuous Galerkin Methods for unsteady incompressible flows
Christoph Lehrenfeld, Joachim Schöberl
In this paper we present an efficient discretization method for the solution of the unsteady incompressible Navier-Stokes equations based on a high order (Hybrid) Discontinuous Gal…
