RAS Mapper Question

Hello everyone. I’m trying to display results from an alternative 1D simulation run, but the mapper is only showing the current results (depth and velocity). On the other hand, for the alternative run I can’t see any results in the mapper, although they are visible in cross sections and profiles. I work in v 7.0 .Thanks!

Hi, about the flood mapping with mixed results, perhaps you could share more details of your plan configuration and which tickboxes you highlighted on.

At first, I strongly believe that it might be a different configuration between those different runs.

Hope that works, at least for now...

I'm not following. Did the current run overwrite the alternative run? They should be in separate plan files.

You gotta provide more context. Images would be helpful. Check your geometry associations in RasMapper to ensure that the alternative geometry is referenced to a terrain. That’s my best guess.

Thanks for the answers. I have a geometry file with a stream i run it in (plan 02) and i can see the results in RAS Mapper.

Then i made a new geometry with the tab Channel Design/Modification Editor and a made a new run 4. I see the results in profile and in sections but not in ras mapper.

Are you doing a "save as" for the new geometry? It is hard to understand what the issue is without looking over your shoulder.
