I am attempting to run a 2D sediment model, and I keep getting the error, “ERROR: Cells Missing Sediment Bed Layers. Make sure all cells have specified sediment bed materials.”
In RAS Mapper, I have created a sediment bed material layer, and within that layer I have created a classification polygon that covers the entire 2D mesh, and associated the geometry I am using with the sediment bed material layer.
The only thing I can think of is that the tab “2D Bed Gradations” in the sediment editor allows me to assign a bed gradation to my classification polygon, but even after I save it once I exit and re-open the sediment editor, the 2D Bed Gradation tab does not show a gradation assigned to the classification polygon. Could this be the issue? How would I resolve this?
Thanks for your help.
