Efficient SSP low-storage Runge-Kutta methods
Roldán Marrodán, Teodoro
; Higueras Sanz, Inmaculada (2019)
Artículo / Artikulua 
In this paper we study the efficiency of Strong Stability Preserving (SSP) Runge-Kutta methods that can be implemented with a low number of registers using their Shu-Osher representation. SSP methods have been studied ... -
New third order low-storage SSP explicit Runge-Kutta methods
Higueras Sanz, Inmaculada ; Roldán Marrodán, Teodoro (Springer, 2019)
Artículo / Artikulua
When a high dimension system of ordinary differential equations is solved numerically, the computer memory capacity may be exhausted. Thus, for such systems, it is important to incorporate low memory usage to some other ... -
Optimized strong stability preserving IMEX Runge-Kutta methods
Higueras Sanz, Inmaculada ; Happenhofer, Natalie; Koch, Othmar; Kupka, Friedrich (2014)
Artículo / Artikulua
We construct and analyze robust strong stability preserving IMplicit-EXplicit Runge-Kutta (IMEX RK) methods for models of flow with diffusion as they appear in astrophysics and in many other fields where equations with ... -
Order barrier for low-storage DIRK methods with positive weights
Higueras Sanz, Inmaculada ; Roldán Marrodán, Teodoro (Springer, 2018)
Artículo / Artikulua
In this paper we study an order barrier for low-storage diagonally implicit Runge-Kutta (DIRK) methods with positive weights. The Butcher matrix for these schemes, that can be implemented with only two memory registers in ...
