matlab计算扩展有限元
用matlab实现扩展有限元计算,有限元法(FEM,FiniteElementMethod)是一种为求得偏微分方程边值问题近似解的数值技术。
它通过变分方法,使得误差函数达到最小值并产生稳定解。
类比于连接多段微小直线逼近圆的思想,有限元法包含了一切可能的方法,这些方法将许多被称为有限元的小区域上的简单方程联系起来,并用其去估计更大区域上的复杂方程。
它将求解域看成是由许多称为有限元的小的互连子域组成,对每一单元假定一个合适的(较简单的)近似解,然后推导求解这个域总的满足条件(如结构的平衡条件),从而得到问题的解。
这个解不是准确解,而是近似解,因为实际问题被较简单的问题所代替。
由于大多数实际问题难以得到准确解,而有限元不仅计算精度高,而且能适应各种复杂形状,因而成为行之有效的工程分析手段
