We are using SRH-2D to model a proposed channel cut in a river. The inlet boundary condition we're using is a variable flow rate with positive and negative values as we have a tidal flow condition. When I run the model, I receive the error shown below. It seems like the negative flow rates are the source of the error. Does anyone know how to allow for negative flow rates in SRH-2D?
Has anyone experienced gaps in boundary conditions (not all cells along a boundary arc are being assigned the boundary condition) with MODFLOW-USG or after converting a structured grid to an unstructured grid? What could be causing this problem? Greg
hello there, of recent i've encountered a typical problem. i've built a mesh for a domain and done a lot of manual editing on it. unknowingly i've lost the land boundary node string, i've tried changing colors, but of no use. ocean nodestring is visible in blue. so 'm sure land node string is gone. is there any automated way to get it back (please don't suggest i've to manually do it). Thanks in advance, great day. --karunakar kintada Scientist
