HEC-RAS Known Issues
HEC-RAS 6.0 has been released! Happy modeling!
Thank you for testing HEC-RAS 6.0 Beta.
Problems with the current beta release (Beta 3) of HEC-RAS 6.0 are listed below. A list of issues fixed can be found here: HEC-RAS Issues Fixed for 6.0 Beta 3.pdf
If you are experiencing a problem not listed here and would like to submit a bug report, please email hec.ras@usace.army.mil with a detailed description of the problem.
Beta 3 released.
HEC-RAS 6.0 Beta 3
Issue | Description | Status 1 2 |
---|---|---|
Toffaleti-MPM transport function bug | The joint, Toffaleti-MPM transport function has included a bug causing significant transport capacity errors (in most 6.0 beta versions). This was fixed in the final 6.0 release. | RESOLVED |
Sediment Hiding Functions | Several of the new hiding functions were not working with 1D sediment transport in the 6.0 beta releases. These were fixed for the final 6.0 release. However, they were fixed very close to the final release and have not been thoroughly tested. So hiding is Beta for 1D models in 6.0. We will remove the Beta tag in 6.0.1. | RESOLVED(Beta) |
Improvements to the 1D Sediment Results Plotter | We made additional improvements to the new 1D sediment plotter. This tool should completely supersede the legacy visualization tools which will be removed from future versions. These include:
| RESOLVED |
Terrain Export | Export of RAS Terrains was resulting in a 1/2 cell shift which resulted in a smoothed terrain surface. | RESOLVED |
Lateral Structure Connected to 2D Flow Area - Flow Error | A new bug came in that seems to be rare. However, a lateral structures connected from a 1D river reach to a 2D Flow Area was producing a negative flow (Flow from the 2D area to the 1D River), even though the 2D area had no water in it. This problem was traced down to a compiler change made between version 6.0 Beta 2 and Beta 3. The problems was fixed and will be in the final release version. | RESOLVED |
3D Viewer Terrain Modification Clip Issue | If the user makes a Terrain Modification that is significantly higher than the highest point in the terrain, the user may experience the modification being clipped when getting near the modification in the 3D Viewer. | RESOLVED |
Bulking-Only Interface/Non-Newtonian Method Selection | We changed the way users select the "bulking only" approach. Instead of selecting "Bulking Only" as a method, users now select "Newtonian" and then set the Cv and choose "Bulking" in the bulking method below. This changed the indexing from the drop down box, so it will impact the backward compatibility of the non-Newtonian editor. Users will have to go in and re-select their non-Newtonian methods | IN PROGRESS |
Precipitation and Wind Force with 1D Modeling | Using spatial precipitation and wind forces at the same time with 1D river reach modeling. This was fixed for the 1D Finite Difference method, but is still an issue for the 1D Finite Volume solution methodology. | RESOLVED |
Plotting From Unsteady Flow Boundary condition Tables | We are moving to a new hydrograph plotting capability. Several of the Boundary Condition Options in the Unsteady Flow Data editor will not allow the user to plot the data. This is a known issue and will be fixed before the final HEC-RAS 6.0 Release. | IN PROGRESS |
Context Specific Help for Sediment and Mud/Debris Flow | Press F1 on the sediment and mud and debris screens and HEC-RAS will take you to the appropriate page of the appropriate pdf manual | RESOLVED |
van Rijn Settling Function Bug | fixed a bug in the van Rijn Setting Function | RESOLVED |
Multiple Variable Sediment Rating Curve Plotter | The new sediment plotter now plots one or more dependent variables against any selected independent variable | RESOLVED |
GDAL Conflict when Opening RAS Mapper | "Error initializing the GDAL path variables. Please check HEC-RAS installation" error message is displayed when attempting to open RAS Mapper. | View Discussion |
1 RESOLVED issues are fixed and will be available in the next release.
2 IN PROGRESS issues are currently being worked on.
