DOF

Degree of freedom. The six DOF options are listed as the following:

1 - X (X-translation will be loaded.)

2 - Y (Y-translation will be loaded.)

3 - Z (Z-translation will be loaded.)

4 - RX (X-rotation will be loaded.)

5 - RY (Y-rotation will be loaded.)

6 - RZ (Z-rotation will be loaded.)

LOAD CURVE ID

Load curve describes amount of load versus time. Refer to Section 14.14.1, Utilities/Load Curve/Create Curve for information about load curve definition.

SCALE FACTOR

Scale factor to amplify or reduce amount of load.

          Select OK as illustrated in Figure 10.11.3 to select nodes. Refer to Figure 5.4.3 for information about selecting nodes.
