</svg> for the Solution of 1D Wave Equation in Polar Coordinates 本地全文： 下载 作者： Venu Gopal ; R. K. Mohanty ; Navnit Jha 等期刊名称： Advances in Numerical Analysis 印刷版ISSN： 1687-9562 电子版ISSN： 1687-9570 出版年度： 2013 卷号： 2013 DOI： 10.1155/2013/470480 出版社： Hindawi Publishing Corporation 摘要： We propose a three-level implicit nine point compact finite difference formulation of order two in time and four in space direction, based on nonpolynomial spline in compression approximation in -direction and finite difference approximation in -direction for the numerical solution of one-dimensional wave equation in polar coordinates. We describe the mathematical formulation procedure in detail and also discussed the stability of the method. Numerical results are provided to justify the usefulness of the proposed method.
