Known Issues

The following limitations and known issues in InfoWorks ICM, version 2024.5, are listed below:

Cloud databases
User permissions cannot be applied to cloud databases. Any member in a team will have access to the team's hub.
Risk objects cannot be copied or created in a cloud database.
TSDB objects cannot be copied or created in a cloud database.
InfoAsset Manager objects cannot be copied, created or used as background networks when working in a cloud database.
Results cannot currently be copied from a cloud database to an on-premise database either directly or via a transportable database.
Result objects cannot be copied to a cloud database. These simulations must be re-run.
Cloud databases do not allow re-runs.
Cloud simulations
Cloud databases have a soft limit of 80 concurrent simulations.
Cloud simulations simulating with GPU compute have a memory limit of 16GB (~20M elements). Larger simulations must be run on CPU.
Risk runs cannot be simulated in the cloud.
Runs with TSDB inputs cannot be simulated in the cloud.
File Geodatabases
When using File Geodatabase in the Open Data Export Centre, files will only be exported to first level folders.
Differences in engine results

Cloud and on-premise simulations may give varying results in numerically sensitive models where the solution is on the edge of a mode (for example pumps on or off), oscillates between modes or has difficulty converging. Although the engine solvers are identical, they are compiled using different mathematical optimisations. Neither result is more accurate than the other.

This behaviour can also occur when running on-premise simulations on different hardware configurations where calculations are distributed across multiple cores, use different processor architecture and/or use of GPU instead of CPU for 2D calculations.

Backward compatibility Release Version Status *DB Update Required
Results from a simulation, run in a 2024.0 and above client, cannot be opened in a 2023.x client and must be re-run. 2024.0 Resolved in 2024.5.3 No
