Visualize Results

Use the Results Explorer to view plots and contours for various result types.

To view the results of the most recent run, do one of the following:
- From the Run Status dialog, click View Current Results.
- From the Evaluate tool group, click the Evaluate tool.
  Figure 1.
The Results Explorer is displayed.
Figure 2.
Choose the result type to contour.
By default, the fatigue results contour shows the total damage/life/safety factor/target stress, and so on.

If the Output event wise results option is turned on in File > Preferences, you have the option to contour total fatigue results or fatigue results specific to an event.
Figure 3.

The visualization types dynamically update based on your selection from the drop-down menu.
Figure 4.
Note:
- The damage shown per event/total is the final damage after multiplied with repeats.
- Session files (.hlf) will retain the fatigue results of each event computed.
Click to toggle the display of results.
Review effected elements in the modeling window.
A legend on the left side of the modeling window color codes damage/life values depending on the result type you select. It also displays the values and IDs of the maximum and minimum elements.
Tip: The values in the legend can be edited to adjust the upper and lower bounds for each color band. Select and change a value then press Enter to dynamically update the legend.
For more information on editing the legend, see Additional Post-Processing Options.
Figure 5.
Review information for specific elements in the following ways:
- Enter an element ID in the Callouts text box. To highlight multiple elements, enter a comma separated list of IDs.
- Click and select elements in the modeling window.
  Figure 6.
Right-click on an element ID and select Delete or Delete All to remove call outs.
Note: Call outs on elements are specific to the event that's contoured.
Plot a damage or rainflow matrix for specific elements and events by choosing an event from the drop-down menu and defining a plot matrix type.
Click to expand the matrix.

By default, the maximum element is plotted. If you add a call out to an element, that element is plotted instead.
Note:
- FOS calculations do not include damage or rainflow matrix plots.
- If the damage of the element from the fatigue event is zero, the damage matrix of the element for that event will be not be available.
- The result contour is not synched with the matrix plots. You should manually change the event toggle in the Plots section to updated the matrix.
- For EN Multiaxial Fatigue, if the strain of the element is larger than the maximum strain, a large damage (10.0) will be assigned to the element without going through the multiaxial damage calculation. In such scenarios, there will be no damage matrix displayed. It is highly recommended you check that the cyclic load is correct. If the cyclic load is correct, you can increase the maximum strain assigned in the Material tool.
- Damage results will show INF contour when damage magnitude is greater than 1e34.

After the run has been completed and the results has been visualized, the fatigue subcase, along with the name of the run, is appended to the Results Browser.

Export Damage and Rainflow Matrix Data

From the Results Explorer, click

above the matrix plot.

A *.rfout file is directly written to your working directory.

The *.rfout file contains the rainflow cycle count for each fatigue event for the queried element highlighted in damage/rainflow matrix.

The total damage, which is the cumulative damage, is written at the end of all event details.
