摘要
Abstract
A parallel vector finite element domain decomposition method is employed to analyze a new-style antenna with waveguide side feed. In this method, edge-based vector elements are employed to avoid the spurious solutions in traditional method of node-based elements. However, on single personal computer, the finite element solution of large-scale problems faces the problems of low operating efficiency and insufficient physical memory. A non-overlapping domain decomposition method is introduced to overcome these problems. The original large domain is divided into a series of small sub-domains, which can be analyzed independently. Hence, this method can easily be parallel implemented to improve efficiency and relieve memory requirement. Numerical experiments of new-style antenna with waveguide side feed demonstrate the accuracy and efficiency of this method.关键词
