Known Issues
This table organizes known issues that are immediately relevant for HEC-FDA users with suggested workarounds and important limitations. The authoritative source of known issues can be found on GitHub.
| Issue Title | Description | Workaround | Status | GitHub Issue |
|---|---|---|---|---|
| Price Index Broken | The price index found under study properties is used to update the inventoried structure, content, vehicle, and other values in the structure inventory from historical price levels to current price levels. The price index does not currently update values and should not be used. | Update structure, content, vehicle, and other values in the structure inventory prior to importing the inventory point shapefile. Attribute fields can be updated using field calculators in your preferred GIS software. | Current in Version 2.0.0 and Version 2.0.1 | Issue 1198 |
| Structure distribution count incorrect for single structure damage pool | The distribution of the quantity of structures damaged by stage is provided among the stage-damage details written to file. This report works ineffectively where the damage pool includes just one structure. The cause is the ineffective way that the statistical tool (histogram) operates for single-valued distributions. | Do not refer to the distribution of structures damaged when there is just one structure being damaged. | Current in Version 2.0.0 and Version 2.0.1 | Issue 1150 |
| Version 2.0.1 has Empty Damage Categories in Stage-Damage Compute | HEC-FDA Version 2.0.1 has a bug that came from an update to the HEC-RAS dependency for reading geospatial data sets. The bug prevents the user from successfully computing aggregated stage-damage functions. Damage categories show up as empty and stage-damage shows zero damage. | The workaround is to use HEC-FDA Version 2.0.0 to compute stage-damage. Open the study in 2.0.0, delete and re-import the structure inventory, then re-run stage-damage compute. Version 2.0.0 is still available in a portable build from the HEC website: https://www.hec.usace.army.mil/software/hec-fda/downloads/HEC-FDA_20_Portable.zip | Current in Version 2.0.1 | Issue 1224 |
| Graphical Uncertainty Incorrect for Edge Cases | HEC-FDA Version 2.0 has a bug that incorrectly interpolates graphical frequency and incorrectly forces monotonicity of graphical uncertainty for edge cases of user provided graphical curves. Curves that appear to be affected are those with many strong changes in shape as exceedance probability decreases. | No workaround is available at this time. The team is hustling to deliver a fix. | Current in Version 2.0.0 and Version 2.0.1 | Issue 1214 |
| Content value from CSVR does not show up in structure detail file. | The structure stage-damage details file provides information about each structure in the inventory, the stages sampled from the hydraulics model, and the corresponding level of damage. Among the structure information provided is content value, but content value only shows up if the structure has a content value in the inventory, the content value will not be reported if being estimated with a content-to-structure value ratio. | Refer to the occupancy type data set to estimate content value for each structure. | Current in Version 2.0.0 and Version 2.0.1 | Issue 1111 |
