Bar/Spring Forces and Moments displays 1D element forces and moments at each end of 1D elements (rods, beams and springs).
The Bar End Loads results application is accessible from the MSC SuperModel main menu.
Symbols indicating the force and moment vectors directions are displayed.
For Bar/Spring Forces and Moments, the Element Force Table produced during an MSC.Nastran analysis is required.
If the elements have properties, the XY plane definition is used to determine the element directions.
The positive results directions for the shear forces and moments are according to the MSC.Nastran convention, see
Figure 5‑1. If a value is negative, the vectors are plotted in the positive directions with negative values.

The Bar/Spring Forces and Moments main form appears as below.
The Display Options button on the previous form accesses a form for the modification of the Bar Forces and Moment Plots display.
A sample component plot appears in
