 *** See next message about line 1705749 from file: zhengche.fem  

 "CTRIAX6   520957       0  353145          353144          118378"    

 This line was interpreted as:  

1705749:CTRIAX6, 520957, 0, 353145, , 353144, , 118378    

 *** ERROR # 1000 *** in the input data:  

Incorrect data in field # 3.  

 Expected INT > 0, found  INTEGER (0).

具体怎么改呢，不知轴对称单元哪里没附上属性
