I am just started using SewerGEMs connect edition. Would you please guide me if some of the feature I used to see in InfoWorks ICM exists in SewerGEMs and how to access it?
1. Data flags so that I can flag the input data based on the source - like from GIS, Surveyed, As-built etc.
2. I used to use GIM in InfoWorks for calibration, Does SewerGEMs has similar features?
3. Does SewerGEMs support Work Group Database Functionality which allows for managing the database form one central location with conflict resolution?
4. Does the SewerGEMs model database act as a central repository for model data management storing GIS/Survey data, other models, and time-series data used within simulations?
5. Does the SewerGEMs offer the interpolation and validation tools to fill in data gap and user-driven SQLs for data clean up, simulation result analysis and automate tedious tasks?
Thank you for your help.

Greetings,
Adding to what Jess said, you can also export shape files or CSV files from ICM and Import them to the SewerGEMS by using the model builder tool. the model nature varies from one to another and everyone has his own way, SewerGEMS has a powerful tool (model builder) with various types of import.
Dear Jesse,
Just would like to remind you about the model run time we have discussed previously, that will be a big revolution to the program if it is reduced significantly, especially in big models with inlet simulation, in addition, to adding the 2D model to sewerGEMS.
Thank you,
Mohamad
Rajendra, we are glad to help.
Regarding importing an Infoworks model - as far as I can tell from their documentation, it appears that ICM is able to export to the standard SWMM5 INP format, which you can then import into SewerGEMS via File > Import > SWMM5. See more here: Importing or Exporting to SewerGEMS, CivilStorm from InfoSWMM, Mike Urban, LandXML, or other competitor product.

Hi Jesse,
Thank you for the information you have provided. It is beneficial. I have a few more questions that I need help for-
Would you please guide me in this regard?
Hi Rajendra,
Please note that I have edited my previous answer to include more details. Additionally, I would like to point out some of the many other strengths of the OpenFlows products like SewerGEMS:

I see that you have also submitted a Service Request with the same questions.
Rajendra Tamrakar said:1. Data flags so that I can flag the input data based on the source - like from GIS, Surveyed, As-built etc.
You can add custom attributes to any element using the User Data Extensions feature. See the following Wiki article for more details. Additionally when importing external data using ModelBuilder, you can choose to create a selection set of imported elements. This can help you flag elements if importing from multiple sources, as you can filter the Flextables based on the selection set and globally edit your User Data Extensions to set values. Or, use Prototypes before running ModelBuilder to set the initial value of your User Data Extensions. See: How to create custom fields using User Data Extensions
Note also that if you are using Change Tracking, you could identify a set of recent edits that you want to set the flag for, select in drawing, and global edit your User Data Extension flag field (via the Flextables for each element type).
Rajendra Tamrakar said:2. I used to use GIM in InfoWorks for calibration, Does SewerGEMs has similar features?
From what I understand, RTK calibration is the equivalent feature in SewerGEMS. See more here: Tips on Sewer Calibration
Rajendra Tamrakar said:3. Does SewerGEMs support Work Group Database Functionality which allows for managing the database form one central location with conflict resolution?
The standard model data repository with Bentley SewerGEMS is ProjectWise. This enables you to control access to the model file and avoid issues that would otherwise occur by storing the model data in a network share. See more here: ProjectWise Integration and Enhancing OpenFlows multi-user workflows with ProjectWise Share
For multi-user workflows, consider using your GIS as the central repository (source of truth), and use ModelBuilder sync workflows to handle cases where multiple users need to edit basic model geometry and attributes. This can include getting additions/fixes (from one or more SewerGEMS users) from the model to back to the GIS (use the GIS for conflict resolution). The Change Tracking feature (which tracks who made changes to a model) can help facilitate identifying and getting things back to the GIS.
Another option for multi-user workflows is submodels. Each user could work on a separate hydraulic model representing a portion of the larger system. Once completed, each of those models can be imported as a submodel (File > Import > Submodel) into the main model, and Change Tracking can be used to identify what has changed.
I have documented the above suggestions in this article: Multi-user Workflows
Rajendra Tamrakar said:4. Does the SewerGEMs model database act as a central repository for model data management storing GIS/Survey data, other models, and time-series data used within simulations?
SewerGEMS models are comprised of a .STSW and .STSW.SQLITE file. All of the hydraulic model data is stored in a SQLITE file. Background layers including survey data and SCADA data are separate files that the .STSW references. Time series hydraulic results are stored in various output files. There is one hydraulic model per database, but scenarios enable multiple what-if situations in the same model (including ability to turn areas of the network on and off with active topology).
In this way, a SewerGEMS model contains all the information needed to calculate, and contributes to an overall digital twin of the system. For example tools such as iModel publishing can push model information to a central repository that would serve as a continuously updated "source of truth".
Rajendra Tamrakar said:5. Does the SewerGEMs offer the interpolation and validation tools to fill in data gap and user-driven SQLs for data clean up, simulation result analysis and automate tedious tasks?
SewerGEMS has many, many tools to help you with interpolation, validation and clean-up. Here are just a few examples:
Element Property Inferencing: this enables you to automatically populate missing elevations and gaps in model data. See: Using Element Property Inferencing to populate missing elevations or elements
Constraint-based design: with the GVF-Rational or GVF-Convex solver, you can provide design constraints and the model will attempt to select suitable pipes sizes and inverts to meet those constraints and provide a good starting point for a network design (on either the whole model or a subset). See: https://www.youtube.com/watch?v=JbhiD23LEIA
Validation: click this button to check the model for connectivity and data entry issues. The User Notification lists provides details for you to review, and you can double click an item to zoom to the location. Additionally, User Notifications will also appear after computing a model, to inform you about potential problems related to hydraulics.
Network Navigator: This tool provides numerous queries to check for model connectivity and other data issues. See: Using Network Navigator
Engineering Standards: this enables you to set your desired range of parameters and generate an alert if a value is outside the range. This is useful for catching data entry issues based on your own set standards. See: Using Engineering Standards
ModelBuilder: this powerful tool enables you to import data from a number of different sources (such as CAD files, Shapefiles, databases, spreadsheets, etc) and convert to model elements. This saves you a lot of time compared to manually laying out elements by tracing over a background. See: Using ModelBuilder to Import External Data
Other features such as Global Edit, Batch Pipe Split, Batch Morph, Network Connectivity Reviewer, and more.
