[求助]UG建模导入ansys后提示线不在面上~

用ug建的一个叶片模型，x_t 格式导入ansys，弹出提示：
line 315 on area 223 is not on the area within a tolerance. this area cold have problems in future boolean operations. (see the BTOL command).
我的叶片是整个的一个体，查看了一下，提示的那条线在一个孔上，
如果不ug修改模型而用ansys处理的话，应该怎么处理？
谢谢了先~~~
若强制划分网格会提示：
232 angles less than 2.5 degrees found in triangle facets of volume 1, with smallest angle=0.13 degrees. poor element quality or mesh failure may result. do you want to continue?
should the vmes command be executed?
a smaller element size specification may give better result.
