Gradient-robust hybrid DG discretizations for the compressible Stokes equations
Philip L. Lederer, Christian Merdon
This paper studies two hybrid discontinuous Galerkin (HDG) discretizations for the velocity-density formulation of the compressible Stokes equations with respect to several desired…

A conforming auxiliary space preconditioner for the mass conserving mixed stress method
Lukas Kogler, Philip L. Lederer, Joachim Schöberl
We are studying the efficient solution of the system of linear equation stemming from the mass conserving mixed stress (MCS) method discretization of the Stokes equations. To that…
