Gravity Loads
Use Home > Gravity in Structure or FEM mode Structure to create an accelerational load on your entire model. See Guidelines for Gravity Loads for more information.
When you define a gravity load, you specify to which load set it belongs. Note that you can have only one gravity load per load set.
When you click Home > Gravity, the Gravity Load dialog box opens with the following items:
Name—The name of the load. The color swatch adjacent to Name allows you to change the color of the icon, the distribution, and the text displayed for the load.
Member of Set—The name of the load set. You can select an existing load set from the drop-down list, or create a new set by clicking New to display the Load Set Definition dialog box.
Properties—Select the coordinate system that the acceleration vector will reference. You must select a Cartesian coordinate system. The default is the current coordinate system. You can select any UCS or the WCS.
* 
If you are working on a 2D model, Creo Simulate uses the coordinate system you specified during the definition of the 2D model as the WCS.
Acceleration—Specify the magnitude and direction of the gravitational acceleration. Select the units of gravitational acceleration. Note that units are of the type length/time2.
Preview—Adds an arrow to your model showing the direction of the gravity load.
After you complete the dialog box, Creo Simulate places a gravity load icon at the origin of the WCS, with a vector pointing in the direction of the load and the letter G at the endpoint of the vector. The gravity load acts at the center of gravity of the part or assembly. Gravity loads that are created for a part are not applicable at the assembly level. In the assembly they are displayed in the model tree with the icon—
