+====== Body Loads ======
 Body loads comprise forces that are distributed over a solid volume. Probably the most familiar of these is the gravitational force acting on a mass to give it weight. Simple gravitational loads are applied in the Specify tab using the Gravity checkbox. Rotational body loads and general linear acceleration loads are applied by choosing **[Add]** in the **Loads** group. Followed by the **__B__ody** option at the command line.

+Gravitational loads are the simplest to apply. Simply check the **[ ] Gravity** checkbox to apply a gravitational load and simulate the model under its own weight. Gravitational loads applied in this manner act in the -Z direction with a magnitude corresponding to Earth's surface gravitation. More complex gravitation scenarios may be simulated using [[#Linear Acceleration Body Loads|linear acceleration loads]]. If the **Gravity** box is checked, the gravitational load is **added** to any other loads being applied.

 The body's response to the linear acceleration is simulated as if the restraints are accelerated in the specified direction. The distributed mass of the body will tend to deflect in the opposite direction.
