Coupling of mixed finite elements and boundary elements
收藏 引用
IMA JOURNAL OF numerical ANALYSIS 2000年 第3期20卷 461-480页
作者: Carstensen, C Funken, SA Univ Kiel Math Seminar D-24098 Kiel Germany
The symmetric coupling of mixed finite element and boundary element methods is analysed for a model interface problem with the Laplacian. The coupling involves a further continuous ansatz function on the interface to ... 详细信息

OPTICS COMMUNICATIONS 2005年 第4-6期255卷 241-247页
作者: Iparraguirre, I Gaztelurrutia, TD ETS Ingn Dpto Fis Aplicada 1 Bilbao 48013 Spain
The problem of transversally gain-limited resonators is studied applying the Fresnel-Huygens integral operator including gain. For simplicity, only symmetric resonators with a Gaussian gain profile confined in a cente... 详细信息

B-spline solution of a singularly perturbed boundary value problem arising in biology
收藏 引用
CHAOS SOLITONS & FRACTALS 2009年 第5期42卷 2934-2948页
作者: Lin, Bin Li, Kaitai Cheng, Zhengxing Xi An Jiao Tong Univ Coll Sci Xian 710049 Peoples R China
We use B-spline functions to develop a numerical method for solving a singularly perturbed boundary value problem associated with biology science. We use B-spline collocation method, which leads to a tridiagonal linea... 详细信息

Global solutions and smoothing effects for semi-linear evolution equations in circular domains
收藏 引用
NONLINEAR ANALYSIS-THEORY METHODS & APPLICATIONS 2008年 第5-6期69卷 1540-1558页
作者: Varlamov, Vladimir Univ Texas Pan Amer Dept Math Edinburg TX 78539 USA
The paper deals with global-in-time solutions of semi-linear evolution equations in circular domains. These solutions are constructed by means of the series of eigenfunctions of the Laplace operator in the correspondi... 详细信息

Stress recovery procedure for solving boundary value problems in the mechanics of a deformable solid by the finite element method
收藏 引用
PMM JOURNAL OF APPLIED MATHEMATICS AND MECHANICS 2010年 第3期74卷 341-348页
作者: Rogovoi, A. A. Stolbova, O. S. [a] Perm Russia
A stress recovery procedure, based on the determination of the forces at the mesh points using a stiffness matrix obtained by the finite element method for the variational Lagrange equation, is described. The vectors ... 详细信息

IMA JOURNAL OF APPLIED MATHEMATICS 1997年 第2期58卷 93-110页
作者: Rogoff, ZM Tew, RH UNIV NOTTINGHAM DEPT THEORET MECHNOTTINGHAM NG7 2RDENGLAND
The coupled wave dynamics of a compressible fluid and an elastic solid are studied when the motion is forced by a nonuniform line source lying in their common interface. The nonuniformity arises as a result of a distr... 详细信息
