RAS Mapper – Velocity output layer not displaying

[Anonymous]

I am running a 1D model in version 5.0.5 created using a recent LiDAR terrain. RAS Mapper shows the calculated Depth and WSE layers, but not the Velocity layer; when I select it, a red asterisk appears next to the corresponding Results layer with the message:

“Error: Some results datasets are missing. The current results file may be from a previous version of RAS. You will need to rerun the model to visualize some output in this dataset.”

I don’t understand why the Velocity layer is not displaying, since velocities are correctly calculated by the program. Is there any solution to this issue?

Thanks,
Marco

Sorry I have no answer to your issue, only another question…

I (also in 5.0.5) have the red asterisk next to Geometries -> Manning’s n -> Final n values. I just tried all the mousing tricks I can think of, and can’t connect the popup message with anything I’ve done (maybe there is a huge delay?), but a few times a message has popped up for an instant about “Geometry is not associated…” That’s all I’ve been able to read before it disappears again.

What did you do to be able to copy your long message?

I haven’t explicitly created a Geometry layer for Manning’s n, I just filled in the table in Geometric Data Editor. I guess that doesn’t automatically import? I’m concerned because in my results View -> General Profile Plot – Weighted n plots, the channel n value is always continuous and correct, but the L/R values are mostly missing and sometimes totally wrong. The original table is still perfect. Maybe that explains my randomly spiky depth and flow results? Velocity can jump from 16 to 600fps for no apparent width or slope reason.

You guys seem to be running out of memory for display

Interesting… “Out of memory” is what the QGIS devs blame for many of my problems. As far as Windows 10 Task Manager or Resource Monitor can see, Ras.exe uses under 50 MB for display, and is very good at clearing that back to ~12 MB when idle. PipeServer.exe (the visible name for RAS Mapper) uses about 160 MB (105 MB of it private…) for my current project.

While Firefox easily claims over a GB for itself, and there are another 5 GB unused. Maybe GIS apps play by different rules?

I see what you are saying. But from experience, models on my desk top that has available memory struggles with large models with multiple plans everytime.

As soon as i go to a 10 TB server the issue never comes up, ever.

It doesn’t seem to be a memory issue — I have tried to save the project to a different file, with only one plan, and the issue persists. Could this be a program bug?

Any luck finding a solution? I am having the same problem.
