提出了6节点映射无限元,4节点双向映射无限元与有限元耦合,分析了一海岸防波堤在浪冲击力的动力特性。结果表明,用这一模型来离散无限域的远场,特别是研究动力问题,具有较好的经济性和可靠性。
A 6-node mapping infinite element and a 4-node bidirectional mapping finite element method are proposed, and the dynamic characteristics of a coastal breakwave impacting on the waves are analyzed. The results show that this model can be used to disperse infinite fields in far fields, especially for dynamical problems, which has good economy and reliability.
