FLEXI: A high order discontinuous Galerkin framework for hyperbolic-parabolic conservation laws
Nico Krais, Andrea Beck, Thomas Bolemann +8
High order (HO) schemes are attractive candidates for the numerical solution of multiscale problems occurring in fluid dynamics and related disciplines. Among the HO discretization…

A large eddy simulation method for DGSEM using non-linearly optimized relaxation filters
David G Flad, Andrea D Beck, Philipp Guthke
In this paper, we apply a specifically designed dissipative spatial filter as sub-grid scale model within the increasingly popular discontinuous Galerkin methods and the closely re…
