Energy-conserving time propagation for a geometric particle-in-cell Vlasov--Maxwell solver
Katharina Kormann, Eric Sonnendrücker
This paper discusses energy-conserving time-discretizations for finite element particle-in-cell discretizations of the Vlasov--Maxwell system. A geometric spatially discrete system…
A Hermite-like basis for faster matrix-free evaluation of interior penalty discontinuous Galerkin operators
Martin Kronbichler, Katharina Kormann, Niklas Fehn +2
This work proposes a basis for improved throughput of matrix-free evaluation of discontinuous Galerkin symmetric interior penalty discretizations on hexahedral elements. The basis…
Stable interpolation with isotropic and anisotropic Gaussians using Hermite generating function
Katharina Kormann, Caroline Lasser, Anna Yurova
Gaussian kernels can be an efficient and accurate tool for multivariate interpolation. In practice, high accuracies are often achieved in the flat limit where the interpolation mat…
