| 摘 要： | 在波动方程的数值模拟中,有限区域建立人工边界吸收边界条件,其中对计算区域角点的处理也是不能忽视的一个问题。PML是一种新的吸收边界条件,这种吸收边界条件几乎达到零反射。重点讨论在使用PML边界条件时,针对计算区域的不同的划分方法做了比较,从而在实际应用中得到更好的数值结果。

| Abstract: | In the numerical simulation of the wave equation,develop an absorbing boundary condition in the finite domain is a very important problem.In which,the handling of corner in the calculation region is also a problem can not be ignored.PML is a new absorbing boundary condition,this absorbing boundary condition almost zero reflection.The use of PML boundary conditions is focuses on,for the calculation of the regional division of the different methods are compared,thus the better numerical results in the practic... |
