Tilake,

There are a couple of problems with the data set you are trying to run with SWMM 5 Beta A. First, as posted on the SWMM web page, Beta A has a bug which fails to convert DW inflow from user units to CFS for internal processing. Second, your 24 hourly pattern factors (which vary from about 0.02 to 0.06) should each be multiplied by 24 so that the daily average DW inflow can be recovered during the simulation. (The sum of the factors should equal the number of factors, not 1.0, to properly describe a repeating variation around a mean value). Finally, the input file you supplied used a '/' as the date separator instead of a '-'. This caused the SWMM 5 GUI to skip over your specified start/end dates and use the current date instead. (We might take a more liberal approach to reading dates in the future, allowing both types of separators.)

When I ran your revised data through Beta B (which fixes the units bug) I got 64 pump starts and a total DW inflow of 124.5 m3.
