CWMS-ResSim Tips

Please ensure your HEC-ResSim model can compute from stand alone program.

Spaces in Alternative Names

Although ResSim allows the use of spaces in alternative names, they are not recommended, especially if you are going to use those alternatives in CWMS or HEC-WAT.  The ResSim plugin for CWMS and WAT use a special ResSim feature called variants (separate copies of the time series mapping (.fits) file of an alternative) to allow an alternative to be use effectively in multiple contexts (stand-alone, in a CWMS forecast run, or in a WAT simulation).  However, if in CWMS or WAT, you create more than one program order and use a given ResSim alternative with a space in its name in different runs set up with different program orders, that alternative may not use the correct variant (.fits) file at compute time.
