The Gravity PropertyManager applies linear accelerations to a part or assembly document for use in structural and nonlinear analyses.

You specify accelerations in the x, y, and z directions of a coordinate system defined by a reference plane or planar face. You can also define linear acceleration along a straight edge.

Gravity loading in each direction is calculated by multiplying the specified acceleration of gravity by the mass. The mass is calculated from the density value of the material. If you select a material from a default library, then the density is already defined. If you choose to input material properties manually, make sure to specify the density. Distributed and remote masses are considered for the supported analysis types.

For nonlinear studies, you can define time-dependent accelerations of gravity.
