A natural decomposition of viscous dissipation in DG methods for turbulent incompressible flows
Christoph Lehrenfeld, Gert Lube, Philipp W. Schroeder
In this note we aim at a characterisation of the discretisation of viscous dissipation which allows to distinguish `physical' (also frequently called `molecular', or `resolved') fr…
Hybrid Discontinuous Galerkin methods with relaxed H(div)-conformity for incompressible flows. Part II
Philip L. Lederer, Christoph Lehrenfeld, Joachim Schöberl
The present work is the second part of a pair of papers, considering Hybrid Discontinuous Galerkin methods with relaxed H(div)-conformity. The first part mainly dealt with presenti…
Mass Conservative Reduced Order Modeling of a Free Boundary Osmotic Cell Swelling Problem
Christoph Lehrenfeld, Stephan Rave
We consider model order reduction for a free boundary problem of an osmotic cell that is parameterized by material parameters as well as the initial shape of the cell. Our approach…
On reference solutions and the sensitivity of the 2D Kelvin-Helmholtz instability problem
Philipp W. Schroeder, Volker John, Philip L. Lederer +3
Two-dimensional Kelvin-Helmholtz instability problems are popular examples for assessing discretizations for incompressible flows at high Reynolds number. Unfortunately, the result…
An Eulerian Finite Element Method for PDEs in time-dependent domains
Christoph Lehrenfeld, Maxim A. Olshanskii
The paper introduces a new finite element numerical method for the solution of partial differential equations on evolving domains. The approach uses a completely Eulerian descripti…
