1. Close the HEC-DSSVue tabulated results window and close HEC-DSSVue.
2. Return to the HEC-WAT main window. From the Study Tree, right-click the FRA simulation name, Existing and the shortcut menu opens. From the shortcut menu, point to Compute, and while holding down the Ctrl keyboard key, click Simulation (CTRL to Force) from the submenu.
3. From the Run FRA Simulation Editor, select the radio 
button for Start At Lifecycle 1, to allow HEC-WAT to run all 10 realizations. Click Next>, note the Lifecycles to Run display [1 – 100]. Click Compute.
- NOTE: While the compute is running, feel free to ask questions or run for a quick break – the compute should take around 5 - 7 minutes, so be back in about that much time.
4. When the compute is complete, close the Compute Progress window and view the precipitation output results by opening the Frequency Viewer. The “realization 1” BASIN AVERAGE frequency curve results should appear the same as in Part Three Step 7.
- From the Realization dropdown list, select All Realizations from the bottom of the list to see all of the realizations plotted together.
- Note, the most extreme realization (high and low) are also labeled as the 90% confidence edges (Percentile 5 and Percentile 95). In the following figure, the confidence interval has been changed to green lines to be more visible.
