Boundary treatment for high-order IMEX Runge-Kutta local discontinuous Galerkin schemes for multidimensional nonlinear parabolic PDEs

V. González-Tabernero, J. G. López-Salas, M. J. Castro-Díaz +1

In this article, we propose novel boundary treatment algorithms to avoid order reduction when implicit-explicit Runge-Kutta time discretization is used for solving convection-diffu…

IMEX-RK finite volume methods for nonlinear 1d parabolic PDEs. Application to option pricing

J. G. López-Salas, M. Suárez-Taboada, M. J. Castro +2

The goal of this paper is to develop 2nd order Implicit-Explicit Runge-Kutta (IMEX-RK) finite volume (FV) schemes for solving 1d parabolic PDEs for option pricing, with possible no…

High-order In-cell Discontinuous Reconstruction path-conservative methods for nonconservative hyperbolic systems -- DR.MOOD generalization

Ernesto Pimentel-García, Manuel J. Castro, Christophe Chalons +1

In this work we develop a new framework to deal numerically with discontinuous solutions in nonconservative hyperbolic systems. First an extension of the MOOD methodology to noncon…
