模型需要添加兩個不同剛度的非線性彈簧，但是通過inp文件添加后，出現沖突錯誤，如下所示：

in keyword *CONFLICTS, file "1.inp", line 208901: Keyword *Conflicts is generated by Abaqus/CAE to highlight changes made via the Keywords Editor that conflict with changes made subsequently via the native GUI.

in keyword *CONFLICTS, file "1.inp", line 208903: Keyword *Conflicts is generated by Abaqus/CAE to highlight changes made via the Keywords Editor that conflict with changes made subsequently via the native GUI.

in keyword *CONFLICTS, file "1.inp", line 208905: Keyword *Conflicts is generated by Abaqus/CAE to highlight changes made via the Keywords Editor that conflict with changes made subsequently via the native GUI.

in keyword *CONFLICTS, file "1.inp", line 208901: The keyword is misplaced. It can be suboption for the following keyword(s)/level(s):

Analysis Input File Processor exited with an error.

刪掉沖突詞條不起作用，而且提示其中一個非線性彈簧語句錯誤，如果改成相同剛度的兩個非線性彈簧或者兩個不同剛度的線性彈簧，則運行時無錯誤提示

請問是什么原因？
