标题: 在Ansys中,用VSBA,ALL,6命令时出现错误:Topological degeneracy detected for VSBA 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。这是什么原因?怎么解决? [打印本页]

相减后产生退化单元,可能是面没有选择好,可以设置boolen 公差(使用BTOL命令),如果公差已经很松弛了,在操作后恢复默认。
