摘要

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。
In this paper, simulating model of 6-node mapped infinite element, 4-node bilateral mapped infinite element and finite element is put forward, and the dynamic characteristic of a coastal breakwater is analyzed using this model. The result shows that model is economic and credible in the discretization of far-field of infinite domain, especially to researching for dynamic problems.
