在abaqus中出现这个错误,改怎么解决
The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained.Either mass must be defined or all of the translational degrees of freedom must be constrained.See the status file for further details.

楼上正解有两个错误,一个是RP没有定义质量,可以按楼上解决,另外你的RP约束的不够,也就是自由度太多,你可以先试一下全约束（约束的最后一个）试试,出正确结果以后再一个一个往回减自由度.Q576190016

你的模型中约束了刚体，然后约束刚体用的参考点没有质量。
解决方法是在interaction模块下，选择菜单栏里面的特殊设置（special）在里面选择惯性，创建参考点的质量。

abaqus中设置材料参数时出现错误请问怎么解决见图在abaqus中出现这个错误,改怎么解决The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained.Either mass must 在ABAQUS中云图只有一种颜色,怎么解决请问你的安装abaqus最后一步出现ABQcaeG.exe应用程序错误的问题是怎么解决的? 在abaqus中提交作业时出现边界条件有一个节点存在不活动的自由度这个错误该怎么办呢,原因又是什么呢? 安装abaqus 出现以下问题,请问怎么解决啊, abaqus中出现下列错误该怎么解决?1 nodes have dof on which velocity/displacement/acceleration/base motion etc.constraints are specified simultaneously.The nodes have been identified in node set ErrNodeBCRedundantDof. 安装Abaqus 6.13.1 过程中出现这样的错误是因为什么?应该怎样解决?如图,到这一步就进行不下去了在solidworks中出现为零的薄壁错误怎么解决 protel99中在PCB中创建网络表显示Node not found这个错误怎么解决? ABAQUS中出现Too many attempts made for this increment错误是什么原因? unity3d中出现：The name `starttimer' does not exist in the current context错误我在这儿定义的,但是总是报如题的错误,该怎么解决? 在abaqus中怎么显示某个方向上的应力在abaqus中实体不在一个平面怎么分区 protel 中出现has no driver该怎么解决~~waiting ! 是错误~~ ABAQUS中Submit提交分析时出现“License for standard are not avaiable”的错误怎么办?谢谢 TomCat中常见错误The requested resource is not available.怎么改初次学servlet,遇到这样的错误一般应怎么改?我想知道出现这种提示,一般的问题在哪些方面?从哪些方面去查错? ansys出现这个错误,怎么改?我用的不是shell单元,因为在网格划分时它会提示shell单元不能划分,这怎么办?
