Optimal Runge-Kutta Stability Polynomials for Multidimensional High-Order Methods
Autor: Siavash Hedayati Nasab, Carlos A. Pereira, Brian C. Vermeire
Publikováno v: Journal of Scientific Computing. 89
In this paper we generate optimized Runge-Kutta stability polynomials for multidimensional discontinuous Galerkin methods recovered using the flux reconstruction approach. Results from linear stability analysis demonstrate that these stability polyno

Accelerated implicit-explicit Runge-Kutta schemes for locally stiff systems
Autor: Brian C. Vermeire, Siavash Hedayati Nasab
Publikováno v: Journal of Computational Physics. 429:110022
In this paper we introduce a family of accelerated implicit-explicit (AIMEX) schemes for the solution of stiff systems of equations. Similar to conventional IMEX schemes, AIMEX schemes allow a problem to be split into its stiff and non-stiff constitu
