【摘要】 有限元网格编码的好坏严重影响有限元法求解的效率和精度以及占用的机器内存 ,为此必须进行网格编码优化。本文基本AD算法编制了网格编码优化程序 ,重点讨论了其中的数据结构问题。做了许多数值例子验证了本程序的有效性及正确性。更多还原

【Abstract】 The mesh code method of finite elements seriously influences the efficiency and precision of finite element calculations,thus mesh code optimum must be done.The program is given for mesh code optimum based on AD method.The data structure for them is emphasisly discussed.Some examples are given to test the vadility and correctness of the program.更多还原
