| 摘 要： | 根据平面有限元网格中边界的特点,利用C++标准模板库(STL)中set、map等容器的数据访问特性,用set分析识别出网格边界,用map将散乱的边界连成环线,建立了识别边界且形成边界环线的快速算法,实现了基于平面有限元网格数据重构网格边界的目的。示例演示了算法的可行性。

| Abstract: | According to the characteristics of the boundary in plane finite element mesh,the data access advantages of set,map and other containers in C+ + Standard Template Library,a fast algorithm is established by using set identifies the mesh boundary and using map links the messy boundary to loop.The algorithm realizes the purpose to reconstruct the mesh boundaries by plane finite element mesh data.The feasibility of the algorithm is verified by a case study. |
