FOURTH-order COMPACT SCHEMES FOR HELMHOLTZ EQUATIONS WITH PIECEWISE WAVE NUMBERS IN THE POLAR COORDINATES
收藏 引用
Journal of Computational Mathematics 2016年 第5期34卷 499-510页
作者: Xiaolu Su Xiufang Feng Zhilin Li School of Mathematics and Computer Science NingXia University YinChuan 750021 China Department of Mathematics North Carolina State University Raleigh NC 27695 USA Nanjing Normal University Nanjing China
In this paper, fourth-order compact finite difference schemes are proposed for solving Helmholtz equation with piecewise wave numbers in polar coordinates with axis-symmetric and in some cases that the solution depend... 详细信息
