VTPSUHM7 - Errors routing storms through basins

[UDjackson]

I am trying to route a 2 year/24 hour storm through an infiltration basin (rain garden and infiltration trenches). VTPSUHM7 while clunky, works well right up to the point of final routing through the basin. I get an error message ("input has caused an error in calculations. Change data and try again."). Then the program crashes. I have used data from another project that I know works and get the same message. Others I have spoken with locally have had the same problem. Does anyone know how to correct this as this is the only program we currently have? Any help would be greatly appreciated. Thanks.

UDjackson - Does your reviewing agency accept other programs for routing? If yes, then use SWMM5 or other free software. Sounds like this program has issues!

I spoke with the programs creator. The problem was resolved by maximizing the number of ordinates in the hydrograph and setting them to zero. For some reason this worked. Thanks.
