以下是ANSYS报错内容:
*** ERROR *** CP = 1793.450 TIME= 10:12:20
An unexpected error ( SIG$SEGV ) has occurred... ANSYS internal data
has been corrupted. ANSYS is unable to recover and will terminate.
Previously saved files are unaffected. Please send the data leading
to this operation to your technical support provider, as this will
allow ANSYS, Inc to improve the program.
实际上可以算完,就是最后会报错,然后ASNSY死掉,不好进行后处理,
我还对上面程序作了一下改动运行:
1)只运行第一个载荷步,结果不报错;
2)把第一个载荷改为:
SFL,3,CONV,50000,,2000
TIME,0.02
AUTOTS,0
DELTIM,0.007,,,1
KBC,0
也不报错。
不知道是什么问题?求各位指教!
