质量和转动惯量的定义

各位大家好，请问质量和转动惯量怎么定义，如何确定质量和转动惯量的大小，error:The deformable element nodes contained in node set ErrNodeRotNodeNoRotInert-Step1 have no rotary inertia associated with them and some rotational degrees of freedom at the nodes are not constrained. Either rotary inertia must be defined or all of the rotational degrees of freedom must be constrained. See the status file for further details.
Error in job Job-1: The deformable element nodes contained in node set ErrNodeSpaNodeNoMass-Step1 have no mass associated with them and some translational degrees of freedom at thenodes are not constrained. Either mass must be definedor all of the translational degrees of freedom must be constrained. See the status file for further details.

Interaction->special->Inertia->Create

具体数值大小这个谁都回答不了你，是由你的实际问题决定的。
