I just installed the new great version of Hec RAS 5.0 and I have some problems with the RAS Mapper. I hope someone can help me. I already loaded my terrain and also the projection and i run my plan with a steady flow simulation. When i open the RAS Mapper it shows me the results layer (Depth, Velocity, Water Surface Elevation as Layer but if check the box in front of the layer to show my results, nothing happens. The conection between results and terrain is correct. I don’t know why this happens. The stored map function works for depth and WSE, but not for my velocity. Why is the ON-the-fly-computation not working? Thanks for your help.
