1.原因:Boolean operations and other solid modeling operations can be unreliable, either failing to work or corrupting/contaminating the database. You should SAVE a copy of your database before a Boolean operation in order to cleanly recover from a failure.
2.办法:
If the geometry is unworkable (no Boolean will work or it cannot be meshed), or if you have encountered a “database corruption” (or contamination) message, then as a work-around use CDWRITE to write out the geometry (CDWRITE,COMB) using the ANF option (CDOPT,ANF) and CDREAD to read it back in (after exiting and re-entering ANSYS) to obtain clean geometry. |
