非重叠Mortar有限元法在电磁分析中的应用
Application of Non-overlapping Mortar Finite Element Method to Electromagnetic Analysis
摘要
Abstract
The mortar element method (MEM) is a new domain decomposition technique. MEM allows to take benefit of the presence of the subdomains in order to choose the discretization method, which is best adapted to the local behavior of the solution of the partial differential equation. In mortar finite element method (MFEI~I) a discretized mortar space is introduced to approximate the original continuous function space. The continuity of degree of freedoms across the non-conforming interface is ensured by the surface integration in a weak sense. The MFEM could "Mortar" the inter face between subdomains effectively. This paper gave the fundamental of non-overlapping MFEM (NO-MFEM); the procedures of calculating the mortar condition were discussed; the calculation and construction of the global matrix was proposed. By two dimensional static magnetic model and three dimensional electrostatic model, the validity of NO-MFEM was proved. This work is fundamental for extending MFEM to the other applications in computational electromagnetics.关键词
