有限元方法是求解偏微分方程的数值方法。它的优点是解题能力强,解题效率高,适合在电子计算机上使用。但人们在计算中也发现有限元法有不少缺点。近年出现了不少改进与新分支。下面简略回顾国内外一些新的探讨,然后重点叙述两个新分支——有限单元半分析法和有限差分法的新趋势。 The finite element method is a numerical method for solving partial differential equations. Its advantages are strong problem-solving ability and high efficiency in solving questions, which is suitable for use on electronic computers. However, people also found in the calculation that the finite element method has many shortcomings. In recent years, there have been many improvements and new branches. The following brief review of some new domestic and foreign discussions, and then focus on the two new branches - the new trend of finite element analysis and finite difference method.
