Perhaps you can start it where the trouble begins.
Try shortening up your model simulation time as much as possible to troubleshoot. But it sounds like you have some instabilities. With 40+ bridges and a 4 to 10 hour run time, this model will be very difficult to troubleshoot. mesh only) do not flatline nor do runs fewer bridges and culverts.ĭo you know anything about this or have any suggestions? It seems to be related to 2D Area Connections, as runs without bridges and culverts (i.e. I have not read about anyone else having this issue, but we have 2 teams working on a handful of similar models of other watersheds, and we have all run into this “flatline” error at some point or another in Beta 2 and Beta 3.
A model which takes 4 hours to successfully run a 7-day storm event instead takes about 10 hours to finish calculating mostly unusable results. Further, the “computations” from this point on take about 2.5 times longer than model runs which do not have this error. Water surface elevation, flow, and structure hydrographs all “flatline”, so to speak. We are running into an issue where the model runs for a time with generally good results, but at some point it stops calculating any movement of water. The 2D area has 40+ bridges and 120+ culverts.

We are working in RAS 6 Beta Update 3 currently with a full 2D model containing a single 2D area, using the rain-on-grid method and diffusion wave equation set. Thank you for the constant excellent content. HEC just released V6 Beta 3 and both of the issues have been fixed from my test run. Thanks for letting us know! Would be good to send that to HEC as a bug report. After I run the model in beta 2, but open it in v5.07, both of the above functions work.

I also have problem with DSS times series plot when I specify, for example, a flow hydrograph for the upstream XS for unsteady flow. It seems the the stage and flow hydrograph function does not work under Beta 6. You have to run 2D areas using unsteady flow. That implies you are running a steady flow simulation. But there’s also a message saying “Steady Flow Simulation HEC-RAS 6.0 Beta”. The messages about the mesh property tables implies you have some 2D areas. Stored maps were not written because the simulation did not complete.Īny help you can provide would be appreciated. \.\src\H5G.c line 285 in H5Gcreate2(): no name HDF5-DIAG: Error detected in HDF5 (1.8.11) thread 0: W-171_West: Mesh property tables are current.

Could you offer any insight on the following error message: I am fairly new to HecRas – so am not sure if this is a bug – or something with my model itself. Check the coordinates of the cross section cutlines and make sure they are correct.Ĭhris – I am running the Beta Version 2 to do a fairly simple analysis. Also, if the cross sections are georeferenced, but the coordinates are wrong, they could be placed in non-sequential order. Unless you created them geospatially with GeoRAS or RAS Mapper. The labels are whatever you assign them and are not tied to the actual spacing between cross sections. Appreciate any direction you can nudge me to for a solution. Any idea on why the river stations numbering are acting this way? I know the label should be the distance between the XS to the downstream of the river, but it seems my XS labels are not following this rule. I’m trying to create a geometry for the bathymetry but the XS labels are not in a consequential manner and thus are connecting XS that are not next to one another creating channels where there shouldn’t be any. Hi Chris, I’m on the 5.0 version of HEC-RAS and I’m having trouble with my XS labels. Use the beta version for testing and training, but better to wait for the official release of 6.0 before using it for a project. This Version supersedes Version 5.0.7, and all previous versions.” I suspect that is a little premature as we are on Beta Version 2.Ĭorrect. Interestingly, the RAS release notes say “Version 6.0 of the River Analysis System (HEC-RAS) is now available.
