A higher-order dual cell method for time-domain Maxwell equations
Lorenzo Codecasa, Bernard Kapidani, Joachim Schöberl +1
We present a higher-order extension of the dual cell method for the time-domain Maxwell equations in three spatial dimensions. The approach builds upon a variational reinterpretati…

Two-level additive Schwarz preconditioners for reduced integration methods
Filipe Cumaru, Alexander Heinlein, Joachim Schöberl
Incompressible fluid flow problems appear frequently in different applications. The discretization of such problems may result in large and ill-conditioned systems of linear equati…

A four-field mixed formulation for incompressible finite elasticity
Guosheng Fu, Michael Neunteufel, Joachim Schöberl +1
In this work, we generalize the mass-conserving mixed stress (MCS) finite element method for Stokes equations [Gopalakrishnan J., Lederer P., and Schöberl J., A mass conserving mi…
