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 Run tools, click the Evaluate tool.
  
  Figure 1.
The Results Explorer is displayed.

Figure 2.
Choose a type from the Result Types menu.
The type of visualizations available will depend on the fatigue module you use for the calculation.
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 3.
Review information for specific elements.
- Enter an element ID in the Callouts text box.
- Click and select elements in the modeling window.
  Tip: Delete an element callout by right-clicking on an element ID and selecting Delete or Delete All.
  
  Figure 4.
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 callout to an element, that element is plotted instead.
Note:
- FOS calculations do not include damage or rainflow matrix plots.
- 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.

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.
