摘要
为提高三维电磁场有限元软件中数据处理的效率,本文研究了二次扫描技术,并就三维有限元软件中地址阵的生成讨论了其具体应用。第一次扫描,通过一次循环确定并存储每个节点的相关节点;第二次扫描,通过另一次循环按存储的相关节点形成非零元素的地址阵。系数阵采用行存储,同时提供按列寻址的地址,实现有限元系数矩阵的快速存储。该方法简单、有效、易于实现。
In order to increase efficiency of data processing in a software package of electromagnetic field using 3D finite element method, the double scan method is studied in the paper. The application example of address matrix formation is discussed. In the first scanning, relevant nodes of all nodes are determined and stored by one iteration. In the second scan, address matrix is formed through stored relevant nodes by another iteration. The coefficient matrix is stored by row storage. Column storage address is also provided. Rapid storage of coefficient matrix in finite element method is then realized. The method is simple, effective and easy to realize.
