An initial velocity is used to simulate a part that is in motion at the beginning of the analysis.
The initial velocity can be either a translational or rotational velocity.
The initial velocity will not be maintained throughout the analysis, it will only be applied at the beginning. External forces may cause the part to slow down or speed up. (To maintain a velocity or specify a velocity versus time function, use a prescribed displacement.)
Apply Initial Velocity
If you have parts selected, you can right-click in the display area and select the Add pull-out menu. Select the Initial Velocity command.
Specify the components of the translation and/or rotational velocities in the Translational Magnitude and Rotational Magnitude sections. If you are applying a rotational velocity, specify the point about which the part is rotating in the Center of Rotation section.
The rotations follow the right-hand rule in the specified axis directions about the specified rotation point. For example, a gear centered at (3, 12, 32) and in the YZ plane would have an initial Rotational Magnitude X and Center of Rotation at (-, 12, 32); since the rotation is about the X direction, the X coordinate of the center point is not important. A positive magnitude would rotate the gear counter clockwise as seen from the YZ-Right view (X axis pointed out toward the viewer).
