Gravity Load—Creo Simulation Live
Gravity loads are body loads that simulate the force of gravity as it affects your model. When you define a gravity load, you specify the components of gravitational acceleration along one of the coordinate directions. A negative value opposes the coordinate direction. For example, if you want to simulate a downward gravitational force of 1G (386.4 in/sec2) in the Y direction, and you are working in in/sec2, you enter –386.4 in the Magnitude entry box and select Y as the direction. If you enter 386.4, the gravitational force would be in the upward direction.
To Define a Gravity Load
1. Click > 
Gravity. The Gravity Load dialog box opens.
Gravity. The Gravity Load dialog box opens.2. Specify a name for the load, or use the default name. Optionally click the color swatch adjacent to the Name box to change the color of the icon, the distribution, or the text displayed for the load.
3. The default coordinate system of the model is the reference coordinate system and is displayed in the Coordinate system collector. In the case of an assembly, the coordinate system of the top level assembly is the default coordinate system. If the model does not have a default coordinate system then the Coordinate system collector is empty.
You can select an alternative reference coordinate system from the Model Tree or Graphics Window.

5. Select units of gravitational acceleration from the drop-down list or accept the default units.
6. Click OK to create the gravity load.
