HEC-RAS 6.6 released
Major Issues
Issue | Description |
---|---|
2D Bridges Connected to Cells with Internal Boundary Conditions Causes Flows to Appear Elsewhere | When a 2D bridge and an internal boundary condition are connected to the same cell, flows from the internal boundary condition are showing up at other location in the model. This limitation means that internal BC lines, georeferenced culverts or gates from other structures, or pumps should not be connected to the same 2D cell as a bridge. An example of this can be found here. HEC-RAS 6.6 will have an error check to prevent geometries with this condition from running. |
1D Sediment Plotter Tabular Data | When you access the 1D sediment results the tabular data does not show up. |
502 Error When Downloading GRiD Files | When attempting to download files from GRiD, the download step will always fail with error 502. |
Bridges In Multiple 2D Areas Prevent Unsteady Flow Simulation from Starting | When there are multiple 2D areas in a model that contain bridges, an error occurs that prevents the simulation from running: "allocatable array is already allocated". |
Simplified physical breaching erodes immediately to max depth. | In at least one data set, the simplified physical breaching algorithm widens at the user-specified pace...but erodes vertically to the max extent almost immediately. |
Avalanching Not Working in 2D Sediment | The interfaces is sending no value for the angle, so the feature is not affecting the result. |
1D Sediment Results Not Reporting Tabular Data | When you run a 1D sediment file, the "Table" is blank (reports "no data to tabulate"). |
Sediment Time Series Boundary Condition Causes the Model to Crash with Fixed Start Times | RAS was not writing the Fixed Start Time for the time series sediment boundary condition, which was crashing the simulation. |
The "Clastic" Non-Newtonian methods (Coulomb and Voellmy) are not working | We have verified that these clastic methods are not producing significantly different results from the clear-water, Newtonian simulations. |
Copy (Ctrl+C) in Attributes Table | When doing a copy in the attributes table in RAS Mapper, additional empty lines may appear when pasting. |
Infiltration Layer not Recognized | When creating a new Infiltration layer, the Infiltration layer is not recognized by the Layer Association dialog. |
Soils Layer not Recognized | When creating a new Infiltration layer, the Soils layer is not recognized in the Create New Infiltration dialog. |
Slope from Measure Tool Incorrect | The RAS Mapper measure tool is reporting incorrect slope measurement. |
Minor Issues
Fixed crash in the computational engine when utilizing Initial Condition points. |
In DSS time series plots, fixed ratio and min value affecting no data values on the plot. |
Fix crash when running a simulation with a paired data or time series plot open. |
Fixed not being able to import point shapefiles that did not have an M field. |
Fixed large landcover datasets being slow to render. |
Fixed infiltration base override columns appearing empty when viewing the infiltration table the first time. |
Fixed "Left Bank Station point is different than the bankline intersection (>1%)" showing in the error layer when it should not be showing. |
Fixed GRiD download always failing with error 502. |
Fixed Model Compare not comparing Culvert Groups/Barrels, Gate Groups/Openings, and Pump Groups/Pumps correctly. |
Fixed "Generate New RAS Terrain" with "Export To Single Raster" option turned on sometimes using an incorrect resampling level, making parts of the terrain appear blurry. |
Fixed global RAS Mapper settings not saving. |
Fixed OBS Stage checkbox not working in the hydrograph plot. |
Fixed vector contour lines not merging sometimes. |
Fixed Infiltration and Percent Impervious not migrating correctly when opening a project in RAS Mapper that was made in a previous version. |
Fixed -3.4e+38 showing as a valid value in DSS Plots. |
Fixed observed data difference plots not showing at all in the Hydrograph plot. |
Fixed property table plot not differentiating different results when more than 1 result is turned on. |
Fixed property table plot not refreshing after changing active plans. |
Fixed the property table plot crashing when it is given a results file that does not have results. |
Fixed "Percent Transition" value not working when the US and DS line had matching top widths or max extents. Renamed Percent Transition to Transition Fraction since it's not really a percent (1 is 100% of the top width). |
For line modifications: 0 slope is now interpreted as 0.001. Blank slope is interpreted as 3:1. This should prevent infinity values in the terrain. |
Fixed selecting an uncomputed stored map in the encroachment polygon generation dialog causing a crash. |
Fixed Update XS Profile from points option not working correctly if there is no associated terrain. |
Fixed being unable to add empty elevation control point layer in RAS Mapper. |
Fixed a crash when trying to edit the colors of a never-before checked landcover layer. |
Fixed USGS topo maps always being downloaded as "attachment". This also fixes not being able to download multiple topo maps at the same time. |
Fixed not being able to download more than 25 files at a time using our downloaders. |
Fixed a crash resulting from plotting profile of newly created 2D bridge in RAS Mapper. |
Fixed "No data to tabulate" always showing in the sediment viewer. |
Fixed the results table in RAS Mapper causing a crash if the user sorts a column then selects a river or reach. |
Fixed being able to paste, cut, and do selected area edits on grayed out columns in RAS Mapper attribute table. |
Fixed find tool loading slow on large 1D datasets. |
Fixed landcover layers always being assigned as type "Landcover". This prevented users from using a soils layer to make an infiltration layer, and prevented users from associating an infiltration layer to a geometry. |
Fixed a rare crash when attempting to filter lines with 0 tolerance. |
Fixed copy in the attribute table adding a new line for each cell above the selected cells. |
Fixed the slope reported from the measure tool in RAS Mapper being incorrect. |
Fixed a rare circumstance where the results profile plot would crash. |
Fixed some false positives with differences for the Model Comparison Tool. |
Made panning while editing a line in RAS Mapper less jarring. |
Fixed 1D structures converting into 2D structures if the upstream XS was moved and the structure's river stationing was not updated. |
Fixed not being able to use lat/long option for downloading data in RAS Mapper. |
Fixed pasting values into attribute tables of structure layers not working correctly in RAS Mapper. |
Fixed Minimum Face Length Tolerance not working correctly. |
Fixed copying Classification Polygons to clipboard taking a very long time. |
Fixed visualization of the station-elevation plot for 2D bridges in the Geometric Data Editor. |
Added back the 2D stage boundary condition to the list of boundaries for 2D sediment transport. |
Fixed a bug with levee overtopping caused by improper handling of first face/cell of levee in the computational engine. |
Fixed issue with culvert barrel centerlines (GIS coordinates) not re-projecting in 2D models when the geometry file that contains them is reprojected. |
Minor Improvements
Improved directional arrow plot option for lines in RAS Mapper. |
The attribute table will now become editable/uneditable according to the corresponding layer's edit state. |
Improved table interaction when interacting with thousands of cells. |
Improved raster contour of the water surface in 2D areas. |
Hovering the cursor in a profile plot in RAS Mapper will now highlight the point at the station where the cursor is hovering. |
Shift+click now works in the 3D Viewer as it does everywhere else. |
Can now switch between terrain line modifications without opening and closing the line modification editor. |
Automatically scale profiles when changing lines representing ground modifications. |
Multi region analysis for encroachment polygons. |
Added a way to generate a new land cover layer using an existing land cover layer. |
For groundline terrain modifications, control points now have priority for a particular station when building the profile of the modification. |
