标题: 在Ansys中,碰到“Topolgical degeneracy detected for ASBA command.Try modifying geometry slightly or loosening the tolerance(BTOL command).If BTOL is relaxed ,be sure to change the tolerance back to the default after operation”,这是什么意思？ [打印本页] 作者: 王鹏 时间: 2013-5-10 15:09 标题: 在Ansys中,碰到“Topolgical degeneracy detected for ASBA command.Try modifying geometry slightly or loosening the tolerance(BTOL command).If BTOL is relaxed ,be sure to change the tolerance back to the default after operation”,这是什么意思？ 作者: 张荣建 时间: 2013-5-10 15:26
公差不能太大，默认公差值是1e-5,每次扩大10倍，即1e-4,1e-3,.....慢慢试试，如果不行，就得检查模型。
