这种情况存在两种可能的原因,其一是这个材料没有定义材料属性,或者材料属性定义不全;其二是为方便后面单元的选取,在定义材料属性的时候虽然定义多个编号,但是定义的内容完全一致,也会出现这个错误,而且这个错误在前处理中不能发现(除非使用check命令),只有在进入求解模块的时候才会被发现。
对于这两种原因,其解决方案也不尽相同,前者是补全材料属性的定义,后者是将材料属性的某个参数做一个微小的改变(可能是0.001),不影响计算,但是也不会出现不同的两组完全相同的MP。

因为你的自己代码里用了NUMC,all命令,然后你的材料编号不连续或是有两种相同参数的材料,所以压缩之后你的材料里面就没有2号材料了。
下面是别人的解释。请参考:
"This is not Ansys error. This is programming error.
You used Numc,all in between after you have defined your geometry.
it compresses the material numbers.
Please check the materilproperties --> material models
you have materials listed from 1 to 5 only.
Where as you named them from 2 to 7.
Since you used Numc,all, now u dont have properties for material 6 .
After using Numc, all you went ahead and defined the material properties for areas as 6.
Had you used this Numc,all at the end of the macro you would not have got this problem. Numc,all at the end of the macro would have compressed the element material properties also."

要素(元素)1需要物质的属性并参考物质的数量,而物质属性没有定义,检查终止。

在preprocessor---material props---change mat num里面把你定义的材料编号(material model里面你的材料最后的数字,只有一个材料的话就是1)与单元号(如果是整个模型单元的话就是all)绑定起来.

给单元1(element 1)设置材料性质,而在设置材料参数之前要先定义相关的材料2(references material numer 2)
