Title: | Jacobian-Free Explicit Multiderivative Runge-Kutta Methods for Hyperbolic Conservation Laws | Authors: | CHOUCHOULIS, Jeremy SCHUETZ, Jochen ZEIFANG, Jonas |
Issue Date: | 2022 | Publisher: | SPRINGER/PLENUM PUBLISHERS | Source: | Journal of Scientific Computing, 90 (3) (Art N° 96) | Abstract: | Based on the recent development of Jacobian-free Lax-Wendroff (LW) approaches for solving hyperbolic conservation laws (Zorio et al. in J Sci Comput 71:246-273, 2017, Carrillo and Parés in J Sci Comput 80:1832-1866, 2019), a novel collection of explicit Jacobian-free multistage multiderivative solvers for hyperbolic conservation laws is presented in this work. In contrast to Taylor time-integration methods, multiderivative Runge-Kutta (MDRK) techniques achieve higher-order of consistency not only through the excessive addition of higher temporal derivatives, but also through the addition of Runge-Kutta-type stages. This adds more flexibility to the time integration in such a way that more stable and more efficient schemes could be identified. The novel method permits the practical application of MDRK schemes. In their original form, they are difficult to utilize as higher-order flux derivatives have to be computed analytically. Here we overcome this by adopting a Jacobian-free approximation of those derivatives. In this paper, we analyze the novel method with respect to order of consistency and stability. We show that the linear CFL number varies significantly with the number of derivatives used. Results are verified numerically on several representative testcases. | Keywords: | Hyperbolic conservation laws;Multiderivative Runge–Kutta;Lax–Wendroff;Finite differences | Document URI: | http://hdl.handle.net/1942/36712 | ISSN: | 0885-7474 | e-ISSN: | 1573-7691 | DOI: | 10.1007/s10915-021-01753-z | ISI #: | 000754210600001 | Rights: | The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2023 |
