Log reports display computational messages from the simulation of a forecast run. The Compute Progress dialog opens when the simulation of a forecast run begins, as shown in the figure below. 

Compute Progress Dialog

CWMS provides status information by model alternative. The Message Bar indicates which model alternative is being simulated, the Current Task Progress Bar indicates the percentage of completion for the current task, and the Overall Progress Bar indicates the percentage of completion of the entire forecast compute. In the example show above, the Message Bar indicates that the HEC-RAS model alternative is running, the Current Task Progress Bar indicates that the HEC-RAS model run is 50% complete, and the Overall Progress Bar indicates the entire compute is approximately 35% complete. When the forecast run is complete, both progress bars will display 100%, and the Message Bar will display Compute Complete.

The information from the Compute Progress dialog is also available in a log report. This log report contains the same information displayed in the Message Output field of the Compute Progress dialog. Additionally, the report gives detailed information regarding model alternatives that were computed.

To view the log file:

  1. Right-click on the name of the forecast run in the Forecast Run Details list and choose Compute Log from the shortcut menu.
