想做一個物體自由下落的6dof+overset仿真,設置了質量和轉動慣量,但是仿真結果是自由落體,實際中這個物體的運動是先自由落體再旋轉下落,需要怎么修改才能達到實際中一樣的仿真結果呢?






For rotational dof make sure that there are no such jumps. All jumps in displacements across steps are ignored There are 3 warning messages in the data (.dat) file.
The nodes have been identified in node set WarnNodeBCIncorrectDof.343 nodes have dof on which incorrect boundary conditions may have been specified.

請問有沒有人能夠提供關于MAT_GENERAL_NON LINEAR_6DOF_DISCRETE_BEAM的具體建模方法?我想做的是建立一個梁,使其在某個范圍內不限制,超過該范圍,將視為剛性沖擊,利用MAT_GENERAL_NON LINEAR_6DOF_DISCRETE_BEAM材料可進行模擬,但我不知道如何設置卡片參數(shù),請問有沒有大佬知道?
