Check Your Understanding
Select the correct option below.
At this point, ANSYS has determined the degrees of freedom at the nodes. If we tweak any of these degrees of freedom, the corresponding deformed shape of the midline will change. How is the total potential energy of the beam affected in the process?
It:
- Decreases
- Stays the same
- Increases

Bending Moment along the Beam
Now, we will set up a solution for the bending moment along the beam. We will do this by setting up a path along the line body. To set up a path, click on in the Outline window. This will launch the Model toolbar in the Menu Bar. In the Model toolbar, press which will bring up the Construction Geometry Tool bar, then press to create a path.
In the Details window, notice that the default path type is Two Points. We need to change that to Edge. Next, using the Edge Selection filter select the line body in the Graphics window. Back in the Details of "Path" window, select Geometry > Accept. Rename it "neutral axis".
Now that we have created the path, we need to create the solver for the bending moment along the beam. Click on in the Outline window to bring up the solution menu, then select Beam Results > Bending Moment. Now that we created the solution, we need to change the parameters so it solves along the path we created. In the Details of "Total Bending Moment" window, change Scoping Method to Path. Next, define the Path parameter to neutral axis (the path we created).
Directional Bending Moment
We would also like to look at the bending moment in a specific direction. Repeat the above step to setup another bending moment solution. In the detail window the new bending moment, change the type to Directional Bending Moment instead of the default Total Bending Moment. Change the orientation to Z axis.
