To run an HMS simulation, you first need to save the HMS file from WMS. Then, start HMS, read the HMS file, and run the simulation in HMS. Finally, you can read the solution back into WMS by opening the HMS DSS solution file from WMS.

To read the solution into WMS, open the DSS file associated with the name of the basin. For example, if the basin name is "Subbasin-3", and the HMS project file name is "castro.hms", you would find a file called "castro.dss" in the same directory as "castro.hms". In WMS, select File | Open and go to the directory where the DSS file that you want to view is located. Open the DSS file and a dialog like the following will show up.

Most hydrographs computed in HMS will have the following information for each part of the pathname:

  • Part A: Nothing
  • Part B: The sub-basin name ("SUBBASIN-3" in our case)
  • Part C: The parameter value ("FLOW" will correspond with the hydrograph for the basin)
  • Part D: The start date for the hydrograph
  • Part E: The time increment for the hydrograph
  • Part F: The HMS Run ID for the hydrograph ("CURRENT" in our case)

Therefore, the entire pathname that we are looking for is "//SUBBASIN-3/FLOW/16JAN1973/5MIN/CURRENT/".

In this dialog, scroll down to find the DSS pathname associated with the basin that you are interested in and select the Edit/Plot Data... button. This will bring your data into the XY series editor where you can see a plot of your output results as shown below.
