We systematically validate the static local mesh refinement capabilities of a recently proposed implicit–explicit discontinuous Galerkin scheme implemented in the framework of …
We conduct a thorough study of different forms of horizontally explicit and vertically implicit (HEVI) time-integration strategies for the compressible Euler equations on spherical …
In the numerical solution of partial differential equations using a method-of-lines approach, the availability of high order spatial discretization schemes motivates the development of …

Dynamical cores used to study the circulation of the atmosphere employ various numerical methods ranging from finite‐volume, spectral element, global spectral, and hybrid methods …
Abstract We propose IMEX HDG-DG schemes for planar and spherical shallow water systems. Of interest is subcritical flow, where the speed of the gravity wave is faster than that …
M Baldauf - Journal of Computational Physics, 2021 - Elsevier
A solver for the Euler equations with optional diffusion based on the Discontinuous Galerkin (DG) method is presented. To be usable for simulation problems in the atmosphere from the …
In numerical time-integration with implicit-explicit (IMEX) methods, a within-step adaptable decomposition called residual balanced (RB) decomposition is introduced. This new …
