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?

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。
