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.
對于這種錯誤，一般從哪些方面修改呢，求助大神啊，三天了還沒解決
