非线性扩散的指数积分器

Exponential integrators for non-linear diffusion

Valentin Dallerit, Mayya Tokman, Ilon Joseph

摘要:

该项目的目标是比较的性能指数时间积分器与传统的方法,如对角隐式龙格-库塔法的背景下解决系统的约化磁流体动力学(RMHD)。在这份报告中,我们提出了初步的概念研究证明的结果表明,指数积分器可以是一个有效的替代传统的集成方案。

英文摘要:

The goal of this project is to compare the performance of exponential time integrators with traditional methods such as diagonally implicit Runge-Kutta methods in the context of solving the system of reduced magnetohydrodynamics (RMHD). In this report, we present initial results of a proof of concept study that shows that exponential integrators can be an efficient alternative to traditional integration schemes.
