AI 中文摘要
本文致力于N维守恒律双曲系统(HCL)解的无扩散计算,特别是简单波的精确逼近。我们开发了LeafNet算法,该算法依赖于:i)将HCL重写为涉及光滑解的耦合系统,以及ii)逼近光滑函数的精确物理信息算法。本文提出了误差估计分析和二维数值实验,以说明所提出的策略。
英文摘要
This paper is devoted to the non-diffusive computation of solutions to $N$-dimensional hyperbolic systems of conservation laws (HCL) and more specifically the accurate approximation of simple waves. We develop the LeafNet algorithm, which relies on: i) a reformulation of HCL as a coupled system involving smooth solutions, and ii) an accurate physics informed algorithms approximating smooth functions. An error estimate analysis and two-dimensional numerical experiments are proposed to illustrate the presented strategy.
