Additional elements included in the Transient Results Viewer "Extended Node Data" tab

Results for additional elements now available in the Extended Node Data tab of the Transient Results Viewer. This data was previously available in the Transient Analysis Detailed Report. With these results now available in the Transient Results Viewer, you can now more easily view these results in graphical and numerical formats.


For air valves, you can find results for Air Volume, Air Head, and Free Air Flow Out.

Valve results will include results for TCVs, FCVs, PRVs, PSVs, PBVs, and GPVs. The results available Valve Percent Closure, HGL (From), HGL (To), and Flow. 

For surge tanks, results include Level, Inflow, and Spill Rate.

The Free Air Flow Out result is the air flow out of the air valve. This is a new result for air valves. If you want to see the pressurized air flow in the air valve used in earlier versions of HAMMER, this will still be available in the Transient Analysis Detailed Report.

More information on the Extended Node Data and using Transient Analysis Detailed Report, see this link: How to view extended node transient results for HAMMER elements.

AutoCAD 2022 Integration

AutoCAD 2022 integration is supported starting with this version of the OpenFlows water products. Support for AutoCAD 2021, AutoCAD 2020, and AutoCAD 2019 is also included.

Bing Maps background transparency

You can enter the transparency for the Bing Maps background, using a value from 0% to 100%. If you have an existing model with a Bing Maps background layer you can edit the background layer by right-clicking on the Bing Maps background layer and choosing Edit. When you set the transparency and click OK, the transparency will be updated.

For more information on Bing Maps backgrounds, see this link: Using Bing Maps as a Background Layer.

Location persistence for Select toolbar

The Select toolbar, which is used in element selection for features like Active Topology, graphs, and other features, will now reopen in the last location used after it was closed. This can be useful to avoid needing to move the Select toolbar from the middle of the drawing if you have zoomed to a given element you want to select.
