Implicit–explicit (IMEX) Runge–Kutta methods for non-hydrostatic atmospheric models [PDF]

open access: yesGeoscientific Model Development, 2018
The efficient simulation of non-hydrostatic atmospheric dynamics requires time integration methods capable of overcoming the explicit stability constraints on time step size arising from acoustic waves.

Dispersion and dissipation error in high-order Runge-Kutta discontinuous Galerkin discretisations of the Maxwell equations [PDF]

open access: yes, 2007
Different time-stepping methods for a nodal high-order discontinuous Galerkin discretisation of the Maxwell equations are discussed. A comparison between the most popular choices of Runge-Kutta (RK) methods is made from the point of view of accuracy and ...

Semiexplicit 𝐴-stable Runge-Kutta methods [PDF]

open access: yesMathematics of Computation, 1979
An s − 1 s - 1 stage semiexplicit Runge-Kutta method is represented by an s × s s \times s real lower triangular matrix where the number of implicit stages is given by the number of nonzero diagonal elements. It is shown that the maximum order attainable is s when

Dissipativity of Runge-Kutta methods for a class of nonlinear functional-integro-differential equations

open access: yesAdvances in Difference Equations, 2017
This paper is concerned with the dissipativity of Runge-Kutta methods for a class of nonlinear functional-integro-differential equations (FIDEs). The dissipativity results of Runge-Kutta methods for the FIDEs are given.

Implicit and Implicit-Explicit Strong Stability Preserving Runge-Kutta Methods with High Linear Order

open access: yes, 2017
When evolving in time the solution of a hyperbolic partial differential equation, it is often desirable to use high order strong stability preserving (SSP) time discretizations. These time discretizations preserve the monotonicity properties satisfied by

Composite group of explicit Runge-Kutta methods [PDF]

open access: yes, 2016
In this paper,the composite groups of Runge-Kutta (RK) method are proposed. The composite group of RK method of third and second order, RK3(2) and fourth and third order RK4(3) base on classical Runge-Kutta method are derived.

A Note on the Construction of Explicit Symplectic Integrators for Schwarzschild Spacetimes

open access: yesThe Astrophysical Journal, 2022
In recent publications, the construction of explicit symplectic integrators for Schwarzschild- and Kerr-type spacetimes is based on splitting and composition methods for numerical integrations of Hamiltonians or time-transformed Hamiltonians associated ...

Relaxation Runge-Kutta Methods: Fully-Discrete Explicit Entropy-Stable Schemes for the Compressible Euler and Navier-Stokes Equations

open access: yes, 2019
The framework of inner product norm preserving relaxation Runge-Kutta methods (David I. Ketcheson, \emph{Relaxation Runge-Kutta Methods: Conservation and Stability for Inner-Product Norms}, SIAM Journal on Numerical Analysis, 2019) is extended to general
