所以,这里改用元胞数组来储存这些基函数的导数,这样我们只需要两个 for 循环就可以搞定了,在更高次元的情形下,这样做的优势更巨大。 phi1x = @(x,y) 2.*x - 1 + 2.*x; phi2x = @(x,y) 0.*x; phi3x = @(x,y) -(2.*(1 - x - y) - 1) - 2.*(1 - x - y); phi4x = @...

Wi**d风 上传 matlab 开发了一个有限元分析计算机程序,该程序使用等参单元(每个单元具有4个节点)来求解线性,静态,二维平面应力弹性问题。 载荷受 2D 点力限制。 边界条件仅限于要应用于节点的均匀位移边界条件。 该程序主要关注任何现代有限元包的“求解器”部分,但是,一些预处理和后处理实用程序,仅用于基本网格...
