网格划分问题
我进行网格划分后，出现下面得错误，是什么意思啊？*** FATAL *** CP= 6.766 TIME= 15:23:23
Divide by Zero in FEM_utNorm. 你用的是不是ansys8.1？
这是ansys8.1的bug
Q: With the simple free meshing of an area as shown by the input below,
ANSYS 8.1 aborts with a division by zero error:

*** FATAL ***
Divide by Zero in FEM_utNorm.
ALL CURRENT ANSYS DATA WRITTEN TO FILE NAME=
ansabort.db
FOR POSSIBLE RESUME FROM THIS POINT
Is this a known bug?The same input works fine in ANSYS 8.0.
A:Yes, Defects 22623, 22725, and 22750 were filed (independently with
similar meshing tasks) and subsequently fixed in ANSYS 9.0 Preview 1.
The fix has also been included in ANSYS 8.1 SP1.This service pack is
expected to be released in the 4th week of June, 2004.As a workaround,
you can issue /NERR,-1,-1,-1 to force the meshing by ignoring the error. 我也是用的ansys8.1啊，是不是这个版本的bug特别多啊，我以前用的时候经常有鼠标选取不灵的时候，
怎么解决呢？
