Guidance (including examples) and solver assumptions in ICM help
Could the ICM help be refreshed/updated and include more examples and/or details of the physics / assumptions / settings used by the simulation solver? Some examples below
- Orifice control – Technical paper “Orifices” (June 2005) is not available anymore. Could this be updated and re-introduced as it was valuable guidance
- Head / discharge curves – “The overall relationship between discharge and head in both directions is represented as a data table of up to 15 discharge values at head values equally spaced by a specified increment.” It seems that more than 15 values can be used and not…4 votesThe orifice control paper is an older CS/SD paper that was not included in the InfoWorks ICM. We can look into updating that for InfoWorks ICM.
The Head/Discharge curve statement appears to be a remnant of HydroWorks. InfoWorks can have an arbitrary number of entries in a head-discharge curve and they do not need to be evenly spaced by head.

"Limiting discharge" field/functionality for subcatchments
For large storm events, not all subcatchment runoff will be able to enter the piped system - inflows will be limited by the size (and condition) of roof downpipes, road gullies, etc. Therefore, I would like for ICM to be able to 'cleanly' deal with this for 1D-only models. There is a work-around where you can route subcatchments through dummy nodes and dummy orifices, making use of the "Limiting discharge" field - but this results in a messy model, where you will likely need hundreds or even thousands of dummy objects. It would be much better if you could directly…

Export a Scenario
For XPSWMM, I would like to have a feature for the scenario manager to export a scenario as a standalone model. Some times, the end user doesn't want to see all the scenarios.
It will be similar to ICM, you can export a scenario as a standalone network.
1 voteXPSWMM will export the current scenario to XPX, or INP as a standalone element.

ICMLive Operator Client - graphs show alert themes consistently
Currently, alert ghe graphs are dynamic and the trace colours set in the template are just used on the traces in order as they are added to the graph.
It is important alert themes are consistent so they communicate flood warnings in a clear. In some projects, the colours of the flood alerts are regulated by law. Adding in confusion by having the colours change creates real risks of the wrong alerts being disseminated.

Easily break into a conduit with a new node
To be able to insert a node (manhole) onto an existing conduit, and have the conduit split at the new node. the node chamber floor would be at the invert of the conduit at that point and that same invert would be assigned to the replacement conduits at that node. The upstream and downstream inverts of the conduit are to remain the same.
I see this as being a very useful tool for designing drainage layouts where it becomes obvious the original layout needs additional pits to meet the required capture rates.
1 voteInfoWorks ICM now supports Conduit Split with the insertion of a node in both InfoWorks and InfoWorks SWMM networks.

Can you add a proposed building elevation directly into the ICM model?
I received the ICM model from the City of San Marcos and was wondering if I can add a proposed building elevation directly into the model to see how the floodplain reacts?
0 votesIn many cases, buildings are added either as voids, or as a mesh or roughness zone.

Ability to run ICM models on older versions of the engine
As a user, I'd like to install the latest version of the ICM UI but run my models using older versions of the engine. This would allow me to work on projects whose results have been generated by previous versions of the engine without having to install the UI just for that project.
Otherwise, when working on projects for different customers I have to install numerous versions of ICM. This quite time consuming, especially when users are restricted from installing software by IT policies.
Ideally, the engine list would only show versions where Innovyze made changes which could impact on…
2 votesWith the release of InfoWorks ICM 2023 and moving forward, the database version will no longer be tied to the UI version. E.g. with the 2023.1 release update, one can open a 2023.0 database, and run the 2023 engine while missing out on the updated elements in the 2023.1 update.

New polygon to represent "buildings" geometry and hydrology
This polygon would allow the user to set the roughness, porosity and flood threshold level all within a single polygon object - negating the need for many overlapping ones. Furthermore, the user is able to set the runoff characteristics for the building. These will be generated as per subcatchment with a single runoff surface and routed to the specified location. Additionally, the user has the ability to set a capacity limit, any flow above this will be capped from entering the 1D network. Instead the flow will be passed out on to the elements surrounding the building. Much as the…

As a user I need to represent and optimise for throttled discharge from subcatchments to node or conduit objects
Many cities are limiting maximum stormwater dicharge to drainage networks.
ICM should include more efficient modelling regarding
- Limiting stormwater flows from subcatchments via throttle requirement (e.g. 0-10 l/s*ha subcatchment), suggesting a new subcatchment data field.
- And quickly analyse how much stormwater (e.g. 10 m³ ) needs to be managed/retained on each subscatchment site via SUDS such as greenroofs, swales, etc. in order to meet and optimise throttle requirements.2 votesThis feature was included it in the 2023.1 update. Check out the What's New for more details. If you have already used it, we would love to hear your feedback on how it is working for you. Thanks again for the great suggestion!

Being able to send ICM Live alerts to a specific Table/DB
Can the system export all the alert lists generated by all models (from one deployment manifest) into a single table or database that can then be exploited by a visualisation software (i.e PowerBI).

cut polygon
It would be nice to have a function in ICM to cut a polygon into 2 pieces by 'drawing' a line Select the polygon object, start the function, then click along the line you want the polygon to be cut into 2 pieces. Both of the resulting pieces should have the properties of the original one.
2 votesI believe what you are looking for may already be feasible using existing functionality. If there is a polygon with a general line object intersecting it, then you can.
1. Select both objects
2. Go to Model > Geometry > Crop overlapping selected objects
3. Reference the entire selection in both drop targets
4. Press “Ok” and the result should be two polygon objects as per the line intersectionThere are some additional options here which can be enabled or disabled as part of the process. If this feature does not meet your needs, then happy to consider further enhancements to it, but for a modelling solution hopefully the geometry functions are already fairly advanced.

FEH13 Peak intensity fix
Fix required for over estimation of summer peak intensities within FEH13 design rainfall brought on by a smaller timesteps being used and not a minimum % of the total duration.
Also to separate out the Areal Reduction Factor and Seasonal Correction Factors for clarity of the data.

Support for overlapping roughness zones in 2D
I have a model that has masses of roughness polygons. invariably some of these overlap. I also have overlapping roughness zones where I have 'donut' features. My life would be SO much easier if meshing didn't fail when the roughness zones overlap. Can we p[ease have the restriction on these relaxed? If we have to specify a priority then that would be acceptable. It doesn't seem to be a problem with HEC-RAS or TUFLOW.... :-)
13 votesA roughness priority field has been added to allow overlapping polygons. This is available in 2023.2.

Select which result variables you want to save
The more functionalities become available in ICM, the larger results files grow and the less manageable they become (especially when running longer time series). In most cases people are only interested in very specific results (e.g. depth, flows, ... and not such things as all the detailed runoff components). So if one would be able to select at the simulation schedule which variables were to be stored), results file sizes (and hence results querying !) could be reduced enormeously.

Variable 2D roughness at low depths
When applying direct rainfall onto 2D zones traditional roughness values do not typically apply, especially where the depths of water on the mesh element are very small. Often the workaround is to apply much higher roughness values in order to 'slow the flow'. It would be helpful to have a depth varying roughness that could be phased out as the water depth increases. This would put ICM in line with how TUFLOW and Flood Modeller Pro deal with the problem.

Route subcatchment outflow directly to a point on the 2D mesh
At times I want to route subcatchment flow to a certain point on the 2D mesh. This could be for directing building runoff to the street/curb or simply making sure the runoff gets to the inlet structure without forcing it into the underground network ignoring inlet capacity.
It would be ideal to simply route subcatchment flow to 2D outfalls or 2D inflow points.6 votesThis feature was recently delivered in InfoWorks ICM version 11.0.2.

Floating licence manager improvements
Updating the floating licence manager (which has to happen occasionally) is very difficult to organise because all licences (clients, engines, …) need to be checked in prior to the update to avoid corruption of the system. In a large company with many users (if not the majority of them) working remotely, this is almost impossible to achieve. So either there should be more flexibility in the update system, or there should be a functionality for a system administrator to force check-in licences if users don't react at the request.
4 votesWith updating licensing coming in 2021, the need to “update” licenses becomes a purely back office issue that removes the need to manually update the license manager.
We’ve avoided this issue by removing the need to force upgrade the licenses. This improvement will retire the floating license manager process by the 2nd half of the 2021 year.
Expect to hear more soon…
