P. To view stress contour of a General UPT beam

To display the full section stress contour on a beam that uses a general UPT profile, use the following procedure.

Stress contours can be displayed for general UPT sections that do not yet have stress distances defined by defining those in the Postprocessing workflow.

On the Results ribbon tab, select the Layouts > Beam Stress tool in the View Results group. The 3D Beam Stress Contour dialog opens.
In the Whole Structure view window, click on any member which uses a General UPT profile to select it.
Either:

select the Define Section Profile tool in the Model group on the Beam ribbon tab

or
right-click and then select Define Section Profile from the pop-up menu

The Define Section Profile dialog opens.
Type the local Y and Z coordinates of the extreme fibers for stress results.
Tip: You can also "swap" the top and bottom sides () or left and right sides () in order to facilitate entering stress points by clicking the corresponding tools.
Click OK.
Use the slider in the Select Section Plane dialogs to update the cross section stress contour display.
(Optional) In the Select Section Plane dialog, type a Y Point and Z Point value to display the cross-section stress at an arbitrary point within the section.
