采用四边形网格划分,利用matlab实现二维拓扑优化问题!-Using quadrilateral mesh, using matlab to achieve two-dimensional topology optimization problem!

Ole Sigmund编写的99行Matlab程序是拓扑优化方面的经典案例。该程序有5个可修改的输入参数：竖直方向网格划分数nely,水平方向网格划分数nelx,保留的材料的体积分数volfrac,惩罚因子penal和滤波器大小rmin。加载方式矩阵F和支承方式fixeddofs也可以分别选取不同的方式或组合。-Ole Sigmund prepared by the 99-line Matlab program is a classic example of topology optimizat
