Subgrid Sampling Technical Preview *
Subgrid Sampling (Technical Preview) is a method for enhancing topographic representation in an InfoWorks 2D model, where the software performs a third clip meshing phase to create a finer triangular mesh for each 2D element inside a 2D zone and any associated Mesh zones, where Subgrid Sampling is to be applied. Subgrid triangles for each 2D element are used to build volume/level tables which, in combination with the 2D face ground levels, define the interface crest levels between 2D elements. See Subgrid Sampling and Subgrid Sampling Methodology for further information.
Using Subgrid Sampling improves InfoWorks ICM's predictive ability without compromising performance speed or result accuracy. The following video highlights the benefits of using Subgrid Sampling:
Using Subgrid Sampling is relatively simple as you only need to check the Subgrid Sampling box and specify the Subgrid Sampling triangle area in a 2D zone or a Mesh zone properties. And if you include a Mesh zone in your model, you can also choose to use the subgrid values specified for it, rather than the ones specified for the 2D zone, by checking the Mesh zone's Override 2D zone Subgrid Sampling box.
There are no licence restrictions for applying Subgrid Sampling to a model. However, to generate a mesh or run a simulation, where a 2D zone or Mesh zone has Subgrid Sampling applied, requires a licence with unlimited elements.
See Using Subgrid Sampling for information about using Subgrid Sampling in a 2D zone or Mesh zone.
As Subgrid Sampling is a Tech Preview, there are a limited set of modelling capabilities, network objects and mesh functionality that can currently be used with it. These are listed in Supported items.
If you try our new Tech Preview feature, we would really appreciate your feedback before it's officially released.

Subgrid Sampling Results
New Subgrid Sampling results, listed below, have been added for 2D zones. These will be available when Subgrid Sampling (see above) is applied to any 2D zones or Mesh zones in your network during a simulation. If the same network includes Network Results Point 2D objects, Subgrid Sampling results will also be available for them.- Mean depth (time-varying), and Max mean depth and Min mean depth (summary).
- Volume (time-varying), and Max volume and Min volume (summary).
- Subgrid flag (summary). Only available for 2D zone results.
See 2D Zone Results Data Fields and Network results points (2D) results for descriptions of the result attributes.
You can use the Property
button on the
GeoPlan toolbar to view all of these results. The Mean depth and Volume results can also be displayed using, for example, the
pick graph
and
pick grid
buttons on the
Results toolbar.
You can also use polygon themes for 2D zones for displaying the Subgrid Sampling results on the GeoPlan. Note that subgrid and non-subgrid elements may be displayed differently. See Special polygon themes for 2D zones for details.
ICMLive for Autodesk InfoWorks ICM Ultimate
ICMLive functionality is now available in Autodesk InfoWorks ICM Ultimate to let you convert hydrologic and hydraulic InfoWorks network models in on-premise databases into near real-time, forecasting systems. See ICMLive for further information.
Database items that are used in ICMLive must reside in a Live group, therefore this type of group and the following items are now available in InfoWorks ICM Ultimate so that you can configure a live system:
- Action List - a list of actions that are triggered based on the generation of a defined Alert.
- Alert Definition List - a list of alert definitions used to alert the user about interesting occurrences in both the data coming from external sources and the simulation results.
- Manifest - a collection of items which will be associated with the InfoWorks network to be simulated in ICMLive Operator Client. Manifests define how simulations are to be run and how they will be displayed in the ICMLive Operator Client (themes, ground models and areas of interested can be selected within the manifest object).
- Manifest Deployment - a collection of manifests which will be available for display in ICMLive Operator Client.
For users who are familiar with ICMLive in ICMLive Configuration Manager, ICMLive in InfoWorks ICM Ultimate works in the same way.
If you have not used ICMLive before, you may find the 1D Urban Network Tutorial helpful for exploring its features.
Autodesk ICMLive Operator Client
This software is now installed with Autodesk InfoWorks ICM as part of the ICMLive system. See ICMLive and ICMLive Design Workflow for details about an ICMLive system.
See the ICMLive Operator Client help for details about using the software.
SWMM network validation
Validation for a SWMM network, where a maximum depth has been set for Junction or Storage nodes, is now significantly quicker.
TSD updates
Updates of a Scalar or Spatial time series data (TSD) can now be performed by InfoWorks ICM as a background process.
Desktop analytics
When you select the Desktop analytics option from the Help menu in 64-bit versions of the software, a new Privacy Settings dialog is now displayed. For 32-bit versions of the software, the existing Data Collection and Use dialog is still used. These dialogs let you choose how we can analyse your usage of our software. By opting in, you help us improve the features, usability, performance and quality of our products.
GeoPlan performance improvements for 2D meshes
The performance of the GeoPlan has been improved when displaying large 2D meshes. You should notice that it is now quicker when you are using, for example, the pan, zoom and properties tools.
CUDA update
An update to CUDA 12.6.3 is included in this release. This means that the NVIDIA drivers for your GPU card may need to be updated to a version that is compatible with CUDA 12.6.3 to ensure that on-premise 2D simulations do not fail. Cards with a compute capability of 5.0 or higher are only supported.
Changes to the help
As ICMLive functionality is now included in Autodesk InfoWorks ICM Ultimate, the help has been updated to reflect this.
This means that the help for ICMLive Configuration Manager, which was previously delivered as a single compiled (CHM) help file displayed in a dedicated HTML help viewer, is now incorporated into the InfoWorks ICM online XML help that is opened in a web browser. You can still access the help by selecting the Help topics option in the ICMLive Configuration Manager Help menu, or by pressing F1 at any time to display the help topic appropriate for that part of the interface.
In the help, the software is referred to as InfoWorks ICM and applies to InfoWorks ICM and ICMLive Configuration Manager unless explicitly stated otherwise.
Similarly, the help for Server Configuration Manager, a component in the ICMLive system, that was previously delivered as a single CHM file, is now included in the InfoWorks Server Configuration Manager section in the InfoWorks ICM online XML help. You can still access the help by selecting the Help button in the Server Configuration Manager application window, or by pressing F1 at any time to display the help topic appropriate for that part of the interface.
