Overview

CONNECT Edition Update 4 (10.04.00.108) of WaterGEMS and WaterCAD introduces improvements and features to help you be more successful.

Note: The original release version was 10.04.00.106. Version 10.04.00.107 was released soon after, with an important update related to saved graphs and how data is presented in these. Version 10.04.00.108 was then released shortly after that with an update to the language of the material and minor loss engineering libraries. If you had install the 106 or 107 version, t is recommended that you upgrade to 10.04.00.108.

New Controls Editor

The Controls Editor has been updated in WaterGEMS and WaterCAD, with a more streamlined and user-friendly interface. Controls are now be edited and created in a table format. All control types are still available, like simple and logical controls, as well control sets.

 

The Controls Editor is available by going to Home > Controls or Component > Controls. The older method for managing controls is still available here as well (but may be removed in a future update).

 

More information on the workflow for the new Controls Editor can be found here: Using Controls, Conditions, Actions, and Control Sets in WaterGEMS and WaterCAD.

Assign DMAs based on Target number of Customer Meters

It is now possible to assign District Metering Areas based on the target number of customer meters. After selecting the Compute button in the District Metering Area tool, a dialog is generated to select the criteria type used to generate the DMAs. In addition to the existing options (Target Number of Nodes and Target Pipe Length), you can also select Target Number of Customer Meters. The workflow will be the same as other criteria types.

 

The following article has more information on modeling DMAs: Modeling District Metering Areas (DMAs) 

Time Step Export Options added to Export to Excel feature

An option has been added to the Export to Excel feature enabling the user to filter the time steps that are exported to Excel.

This feature will be useful to limit the number of rows exported out to Excel and decrease the time needed to export the data.

Note: if you exceed the limit of the number of rows for Excel, select CSV for the "Format".

For more information on the Export to Excel feature, see the following link: Export data to an Excel spreadsheet. 

EPANET 2.2 Support

WaterGEMS and WaterCAD now support the EPANET 2.2 engine (numerical solver). Along with this, additional 2.2-specific convergence options have been included with this release. A model using the "EPANET 2.2" engine should match the results in EPANET 2.2, while the "WaterGEMS 2.2" engine is based on the EPANET 2.2 engine but with additional improvements.

More information on engine compatibility and calculation options properties can be found at this link: Engine Compatibility Mode and related Calculation options.

Tank overflow support

Support for tank overflows have been included in this release. This feature will be available if you are using the WaterGEMS 2.2.0, WaterGEMS 2.00.12, WaterGEMS 2.00.10, or EPANET 2.2.0 engines in the Calculation Options.

To use this feature, open the tank Properties grid and set the property field “Allow tank overflow?” to True. With this setting, the tank can overflow during the simulation.

 

If “Allow tank overflow?” is set to True and the tank is full, you will see a user notification that the tank is overflowing. In addition, if “Allow tank overflow?” is set to True, the built-in tank altitude valve is not used. This means that there will continue to be flow to the tank if the tank is full.

More information on the expected operation when a tank is full or overflowing can be found here: What happens when a tank becomes empty, full, or overflows?

New convergence options

The EPANET 2.2 based engine introduces two new calculation options for convergence.

These values are used to make convergence stricter in either terms of flow or headloss. In other words, a limit is set for the largest flow or headloss change in a link, before convergence can be deemed to have occurred.

Continue if Unbalanced calculation options

With the “Continue if Unbalanced?” calculation option, if the run exceeds the maximum number of trials without reaching convergence, WaterGEMS and WaterCAD will continue to try additional trials up to the value entered for the Extra Iterations feature.

To use this feature, set “Continue if Unbalanced?” to True. If this is set to False, no additional time steps will compute beyond the time step that is unbalanced and the analysis will stop.

Bulk Archive feature for Change Tracking

A new bulk archive feature is available for change tracking. With this, you will be able to archive a large number of items from the Change Tracking database. This will remove the items from the model database file and store the archived changes in an external database file.

You can access this by going to the Review tab. Note that this does not replace the Archive feature in the Change Tracking manager.
