Construction of additive semi-implicit Runge-Kutta methods with low-storage requirements
Higueras Sanz, Inmaculada
; Roldán Marrodán, Teodoro (Springer US, 2016)
Artículo / Artikulua 
Space discretization of some time-dependent partial differential equations gives rise to systems of ordinary differential equations in additive form whose terms have different stiffness properties. In these cases, implicit ... -
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 ... -
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 ... -
Strong stability preserving properties of composition Runge-Kutta schemes
Higueras Sanz, Inmaculada; Roldán Marrodán, Teodoro (Springer, 2019)
Artículo / Artikulua
In this paper Strong Stability Preserving (SSP) properties of Runge Kutta methods obtained by com- posing k different schemes with different step sizes are studied. The SSP coefficient of the composition method is obtained ...
