This section lists any bugs that have been fixed between versions 2024.1 and 2024.2 of ICMLive Operator Client.
Pre 2024.0 release notes can be found here.
See Known Issues in 2024 Versions for a list of limitations that we are aware of.
The fixes listed below are those that are viewed as likely to impact on users in an unexpected way, mainly changed simulation results, or differences in behaviour that might not be obvious.
Any fix marked with an asterisk (*) requires a database update to database version 2024.2 in order to access the fix.
Infiltration
The infiltration depth and volume at network results polygons (2D) in models containing only infiltration surfaces of type "fixed" was always reported as nil. This issue only affected simulations carried out on a GPU. It has been fixed.
Display scaling
An issue with the size of text and toolbar buttons when a high display scaling is selected in Windows has been resolved.
Pollutant concentration in force mains
Simulation results were showing zero concentrations of pollutants in force mains if the level is below the invert. This has been corrected.
Pollutants in force mains
Pollutants are now propagated downstream in force mains even when the depth is negative.
Importing inflows from XPSWMM
Inflows are now imported from hydraulics only XPSWMM models.
Job control status for cloud simulations
When results are being downloaded from a cloud simulation, the status in the job control window now shows the correct status.
Measure distance tool with a Viewer licence
An "invalid pointer" error when using the measure distance tool using a Viewer licence (or a full licence supporting viewing of networks in a different product) has been fixed.
Clip meshing robustness
Improvements have been made to the robustness of clip meshing relating to intersections of triangles with user data. This should reduce the instance of "Fatal 34: ASSERT" errors in 2D simulations. A re-mesh is required in order to benefit from these enhancements.
Initial conditions in 2D simulations *
Where an initial conditions object is used as well as a simulation providing initial state, the initial conditions override the simulation's state. This was not reflected correctly in the maximum results for 2D zones. It is now.
Modelling algae in 2D
A crash in simulations modelling algae in a network with a 2D zone has been fixed.
Rainfall profiles
Network Results Polygon (2D) now report the correct rainfall profile in results. When spatially varying rainfall is used, the profile with the biggest coverage of the polygon is reported.
Resampling ground models
A crash when viewing 2D zone properties after resampling a ground model has been fixed.
2D element properties
A very occasional invalid pointer when when using the 2D element property tool with older database versions has been corrected.
Networks results polygons
Results for a network results polygon (2D) on the edge of a 2D zone or void did not include the portion of the polygon touching the edge or void. This has been rectified.
InfoWorks ICM Standard/ICMOne
A crash when a second user tries to access a database with a Standard or ICMOne license has been fixed. Standard and ICMOne licenses continue to support only single-user access to databases.
Area averaging of spatial rainfall with overlapping subcatchments
When using spatial rainfall with overlapping subcatchments, area averaging was not being applied to all subcatchments and was being applied unpredictably. This has been fixed.
Flood theming in SWMM networks
Flooding simulated in 2D can now be themed on the GeoPlan in SWMM networks.
Shape factor in SWMM simulations *
Simulations in SWMM networks were always using the default shape factor. The user-specified factor is now applied when using a database of version 2024.2 or later. Databases with version 2024.1 or earlier continue to use the default shape factor.
Volume results precision
The precision of volume results reported at nodes has been increased by two decimal places.
RTK unit hydrographs in SWMM simulations
SWMM simulations were not always using the specified RTK unit hydrograph. This has been corrected.
