-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_load|linear acceleration loads]]. If the **Gravity** box is checked, the gravitational load is **added** to any other loads being applied.+Gravitational loads are the simplest to apply.

 Rotational body loads are applied by choosing **[Add]** in the **Loads** group of the **Specify** tab. Choose the the **__B__ody** option at the command line to bring up the **Body Load Creator** dialog. Rotational body loads are applied by choosing **[Add]** in the **Loads** group of the **Specify** tab.

 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. The body's response to the linear acceleration is simulated as if the restraints are accelerated in the specified direction.
