Definitions

Field Contents SI Unit Example
SID Load set identification number.

(Integer > 0)

  
G1 Grid point identification number.

(Integer > 0)

  
C Component number (Integer 1 through 18). The component refers to the direction and type of motion of the grid point G1 in the Basic Coordinate System (not the Local Coordinate System).  
G2 Grid point identification number to define relative motion.

(Integer > 0 or blank)

  
EID Expression identification number of the MBVAR entry that gives the motion vs. time.

(Integer > 0)

  
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. The types and directions of motion for the component numbers are given in the following table.
    Component Number(s) Motion Type Direction(s) of Motion
    1, 2, and 3 Displacement X, Y, Z
    4, 5, and 6 Rotation X, Y, Z
    7, 8, and 9 Translational Velocity X, Y, Z
    10, 11, and 12 Angular Velocity X, Y, Z
    13, 14, and 15 Translational Acceleration X, Y, Z
    16, 17, and 18 Angular Acceleration X, Y, Z

    The component numbers and directions of motion are in the format: 1->X, 2->Y and 3->Z for Displacement and this format is followed for all the types in the table.
