This topic lists any bugs that have been fixed between versions 2025.4 and 2025.5.1 of InfoWorks ICM.
See Known Limitation and Issues for a list of limitations and any issues 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.
InfoWorks ICM 2025.5.1
Database update scripts
The scripts for updating Oracle and SQLServer databases from version 2025.2 to 2025.3 were missing from 2025.4 and 2025.5 installers. They have been reinstated.
Performance of on-premise 2D simulations on a CPU
A performance degradation in 2D simulations run on a CPU from a non-cloud databases introduced in version 2025.4 has been rectified. This regression did not affects GPU or cloud simulations.
Flow into buildings
A regression introduced in 2025.3 meant that buildings were not behaving in a porous way (i.e. water was not flowing into buildings) and the "flow into buildings" result reported was an arbitrary value. This has been fixed.
Copying networks to cloud databases
Networks copies into cloud databases from Workgroup databases on which the archive tool had previously been used were sometimes missing data. This problem would only occur if all of the following apply:
- The network being copied has been modified by the archive tool and there is an archive file.
- The network was copied to the cloud with a 2025 version of the software.
- The network has branches.
- Some data in a branch has been archived.
- New objects have been created in a branch and in the trunk.
This issue has been fixed.
ARR and NOAA storm generators
The ARR and NOAA storm generators were not available in 32 bit versions of InfoWorks. They have been reinstated.
Vulnerabilities
The following security vulnerabilities have been addressed:
CWE-787, CVE-2024-9681
See the Autodesk Trust Center for details about vulnerabilities in InfoWorks software.
InfoWorks ICM 2025.5
Long sections of SWMM networks
A minor error where ground shading was occasionally applied inside pipes in the long section of SWMM networks has been corrected.
Descriptions in cloud databases
Descriptions of objects in the tree view should now be displayed correctly for databases in the cloud.
XPSWMM import
A crash in the XPSWMM/XPStorm importer has been fixed.
2D objects with non-ASCII characters
A "not found in Network" error when opening results using 2D objects with non-ASCII characters in their names has been corrected.
Rational routing method
The rational routing method now calculates the correct effective rainfall if the time of concentration is not an integer multiple of the rainfall timestep.
Simulation failure with gauged subcatchments
If a large number of subcatchments are gauged (around 12000), then simulations were sometimes failing with an error "stderr: forrtl: severe (174): SIGSEGV, segmentation fault occurred" in the log. This regression was introduced in version 2025.1 and has now been fixed.
ReFH soil moisture content
The soil moisture content was being reported incorrectly when zero-area ReFH surfaces are defined before one with a non-zero area. This could happen if you defined the ReFH surface after blank surfaces on a land use. The actual runoff values were unaffected by the defect, which has been fixed.
Meshing errors
Some "Error in triangulation process" messages in the mesh log have been replaced with more specific information.
ICM Exchange
The "mesh_async" method in ICM Exchange is now available in the Ultimate version of InfoWorks ICM.
Copying networks to cloud databases
An issue with uploading networks containing large objects (such as 2D zones) to cloud databases has been improved. Such actions will no longer time out after 20 minutes.
Merge changes from another network
When merging changes from one network to another, the 'Use location for matching' option could sometimes result in an "unexpected field type" error, following which the target network could not be used. This has been fixed.
Crashes in grid windows and tree view
Intermittent crashes in grid windows and in the Import right-click menu on model groups have been fixed.
Maximum mesh size
A reduction in the maximum number of triangles that can be generated in a mesh, which was introduced in 2025.4, has been reverted.
Vulnerabilities
The following security vulnerabilities have been addressed:
CVE-2024-7991, CVE-2024-7992, CVE-2024-8896, CVE-2024-9489, CVE-2024-9996, CVE-2024-9997
