Asymptotic-Preserving Exponential Integrators applied to the Hyperbolic Korteweg-de Vries System
Abhijit Biswas, Sebastiano Boscarino, David I. Ketcheson +1
We study the application of exponential time integration methods, coupled with Fourier pseudospectral space discretization, to the hyperbolic Korteweg-de Vries (KdVH) system. We in…
An Adaptive Fourier Spectral Method for the Vlasov-Poisson system
Seung Yeon Cho, Giovanni Russo
Numerical simulation of the Vlasov-Poisson system faces fundamental challenges due to phase-space filamentation. Standard spectral methods rely on artificial filtering to suppress…
Activation and Avalanche Length Scales in the Finite-Temperature Creep of an Elastic Interface
Giovanni Russo, Ezequiel E. Ferrero, Alejandro B. Kolton +2
We investigate the creep dynamics of a driven elastic line at finite temperature, well below the depinning threshold. We show that creep is governed by two distinct length scales.…
An efficient implicit scheme for the multimaterial Euler equations in Lagrangian coordinates
Simone Chiocchetti, Giovanni Russo
Stratified fluids composed of a sequence of alternate layers show interesting macroscopic properties, which may be quite different from those of the individual constituent fluids.…
A quantitative comparison of high-order asymptotic-preserving and asymptotically-accurate IMEX methods for the Euler equations with non-ideal gases
Giuseppe Orlando, Sebastiano Boscarino, Giovanni Russo
We present a quantitative comparison between two different Implicit-Explicit Runge-Kutta (IMEX-RK) approaches for the Euler equations of gas dynamics, specifically tailored for the…
A semi-implicit finite volume method for the Exner model of sediment transport
S. Avgerinos, M. J. Castro, E. Macca +1
The aim of this work is to construct efficient finite volume schemes for the numerical study of sediment transport in shallow water, in the framework of the Exner model.In most cas…
Well-balanced adaptive compact approximate Taylor methods for systems of balance laws
H. Carrillo, E. Macca, C. Pares +1
Compact Approximate Taylor (CAT) methods for systems of conservation laws were introduced by Carrillo and Pares in 2019. These methods, based on a strategy that allows one to exten…
