Contents |
|
SID |
Load set identification number. (Integer > 0) |
|
G1 |
Grid point identification number. (Integer > 0) |
|
C1 |
Component number (Integer 1 through 18). The component refers to the coordinate system referenced by the grid point G1. |
|
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
A CID of zero or blank references the basic coordinate system.
The component numbers 1, 2, 3 belong to the three displacement directions; 4, 5, 6 to the three rotations; 7, 8, 9 to the three translational velocities; and 10, 11, 12 to the three angular velocities; 13, 14, 15 to the three translational accelerations; and 16, 17, 18 to the three angular acceleration.
