adina 建模时,重复点和面如何过滤掉啊
各位好!请问adina 建模时,重复点和面如何过滤掉啊 AINDA允许重复的几何,好像没有过滤的法子。 谢谢,但这样会影响计算吧,甚至不能计算 因为有重复的点线等,所以加载及边界条件出现错误的可能性就大了很多。重复的几何能影响计算,还没有遇到过这事。 我遇到了这样的问题,流体模型为三维,固体模型也是三维,用面旋转生成3D模型,在设置流固耦合边界条件时,由于在不同的体中面的号码是不一样的,因此存在了选择的问题,不过在计算过程中,没有出现边界条件设置出错的问题。不过流固耦合计算没能收敛,提示:

目前还不知道怎么解决?请高人指点。 你这个问题是否是应为施加载荷太大,导致局部变形出现变异,不能收敛啊 我也遇到同样的问题,无法解决
