5 By default, the color bar is positioned in the upper-left corner. Select an
appropriate option under Position to place the color bar at a different
location.
6 For Size, select an appropriate option to resize the color bar, and then
click OK.
The color bar settings are applied on a per result basis.

Read Stress Analysis Results

When the analysis is complete, you see the results of your solution. If you did
a stress analysis, the Von Mises Stress results set displays. If your initial analysis
is a natural frequency analysis, the results set for the first mode displays. To
view a different results set, double-click that results set in the browser pane.
The currently viewed results set has a check mark next to it in the browser.
You always see the undeformed wireframe of the part when you are viewing
results.

Interpret Results Contours

The contour colors display in the results corresponds to the value ranges shown
in the legend. In most cases, results displayed in red are of most interest, either
because of their representation of high stress or high deformation, or a low
factor of safety. Each results set gives you different information about the
effect of the load on your part.
Von Mises Stress
Von Mises stress results use color contours to show you the stresses calculated
during the solution for your model. The deformed model is displayed. The
color contours correspond to the values defined by the color bar.
1st Principal Stress
The 1st principal stress gives you the value of stress that is normal to the plane
in which the shear stress is zero. The 1st principal stress helps you understand
the maximum tensile stress induced in the part due to the loading conditions.
