Means displacement motion
  
D0 Initial displacement if motion data is of type velocity or acceleration, ignored otherwise.  
V0 Initial velocity, if motion data type is acceleration, ignored otherwise.  

Comments

  1. Joint motion can only be applied to cylindrical joints (MTYPE = TRANS or ROT), revolute joints (MTYPE = ROT), and translational joints (MTYPE = TRANS).
  2. The MOTNJ Bulk Data Entry should be selected in the MOTION Subcase Information section, if it is to be included in the analysis.
