怎样给ABAQUS中的刚体参考点定义mass？

Youngchen

出现如下错误提示：The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass-Step0 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.
请教朋友怎么样在ABAQUS中给刚体参考点定义mass？

zsq-w

Interaction步---special菜单---inertia--Create  选取相应的RP --point mass/inetia

如果参考点不是完全平动约束，必须定义质量，如果不是完全转动约束，就必须定义转动惯量
