Out of range message or convergence problems for a weir that outfalls into a culvert.
Typically, this occurs whenever the user is trying to model an inlet box structure as a weir. If there is a box (or standpipe) structure that is discharging directly into an underground culvert, then try modeling the structure as an inlet box (or standpipe) discharging into a culvert.PondPack has a special algorithm that will check whether the inlet box (or standpipe) is operating under weir or orifice conditions, and whether the downstream culvert is the controlling flow element. The user can specify theweir and orifice coefficients pertinent to each case.For standpipe and inlet box examples, refer to the example file Riser.ppw that was installed with PondPack. A profile view of the standpipe for this example is provided via the Outlet Connectivity Example help link provided on the main outlet editor dialog.
