LS_dyna运行中出现如下图中错误，请会的人帮忙解答一下

节点1重复定义了。查看k文件节点部分！！！不要谢！女雷锋而已！

*** Warning 10861 (KEY+861) Missing *ALE_MULTI-MATERIAL_GROUP definition for ALE multi-material formulation 11. All parts defined with ELFORM=11 will be taking material properties of the first defined ELFORM=11 *PART. *** Error 11119 (KEY+1119) Contact surface ID 1 needs MSID to be set to non-zero since it is not a single surface contact type *** Error 10133 (KEY+133) input data failed with: 2 errors

看最后一句 是说总共有一处错误 重复定义材料1
