In our example, there are no Body (Acceleration) Loads, so this step can be skipped.
Click 
to define Body (Acceleration) Loads, in case there are any. For details, see Body (Acceleration) Loads.
The Body (Acceleration) Loads form appears.
Click OK to exit.
Note: If the want to take into account the self-weight of Elements as an additional elemental load for each Element, we have to provide the Material Density for the Material of each Element (we have done that in this example) and also to define a Linear Acceleration Vector equal to the standard earth gravitational acceleration. We should set the earth gravitational acceleration with a minus (-) sign at the Y direction, i.e. gravity acting towards -Y global axis.
Using the Default Metric System of Units, we need to input -9.80665, or simply -9.81, at the aY component of the Linear Acceleration Vector and then press ENTER on the keyboard. The program will automatically calculate the self weight (in kN/m) for each Element, as a Y-Body Load. All properties on the table are read-only properties.
