18、.使网格更加平滑的过渡4. 离散变量参数在拓扑优化中可用于使具有中间密度值得单元趋向于1或者0,减少密度在0到1之间的单元数量,这样可以得到更加离散的结构.Discrete 离散参数用于2D和3D单元.2D单元推荐的取值范围为02, 3D推荐的范围 为03.使网格最后更加离散化5. 迭代终止条件是定义迭代终止的规那么,即当相邻两次迭代目标函数值的变化 小于规定条件,同时满足于约束条件时结束优化迭代.根据优化时目标函数 的数值大小定义.此处定义目标容差 Objtol=0.005只设置离散变量参数为1只设置棋盘格数为 3离散变量参数为1 ；棋盘格数为3什么也没有设置加载方式,四顶点加载向下 20N的力,底部中央位置施加全约束.6.*ERRO
