The Semi-Discrete Method for Solving High-Dimension Wave Equation
-
摘要: 本文用半离散方法将高维波动方程离散为一维耦合波动方程组。文中给出了离散的收敛性及一维耦合波动方程组的适定性结果。数值例子表明这种方法收敛速度是很快的。Abstract: The article gives a semi-discrete method for solving high-dimension wave equation.By using the method,high-dimension wave equation is converted by means of discretization into 1-D wave equation system which is well-posed.The convergence of the semi-discrete method is given.The numerical calculating results show that the speed of convergence is high.
