I am running an unsteady model in HEC-RAS 5.0. I have a a lateral inflow hydro-graph nearing the downstream section of my model. When I run the unsteady plan file I keep getting a warning about max iterations at the cross section where I have the inflow hydro graph boundary condition set. I have raised the number of iteration up to 40 and have tried interpolated cross sections both downstream and upstream of the problem cross section but I keep getting the error. Has some else encountered something like this? Please let me know. Thanks.
Ps. I have another lateral inflow hydrograph several x-sections upstream of this one and that gives me no error.
