Spectral Elliptic Solvers in a Finite Cylinder
收藏 引用
Communications in Computational Physics 2009年 第2期5卷 426-441页
作者: F.Auteri L.Quartapelle Politecnico di Milano Via La Masa 3420156 MilanoItaly
New direct spectral solvers for the 3D Helmholtz equation in a finite cylindrical region are presented.A purely variational(no collocation)formulation of the problem is adopted,based on Fourier series expansion of the... 详细信息
