eWater is pleased to announce the latest Production Release of Source version 5.12. Key enhancements in version 5.12 include improvements to Complex Supply Point Distribution Loss, improvements to the Urban Developer Plugin and a number of minor issues.
Supply Point Distribution Loss in Source
The editor has been simplified and the logic as well. There are now also more recorders for each individual loss. It now makes it clear that the proportion is of Supplied demand, rather than demand.
You can now model 10 different individual components of Distribution Loss at a Supply Point. This is on an optional, separate tab:
Urban Developer
We have improved the User interface performance when editing models in Urban Developer and we have enabled Urban Developer to run as a sub-model by Source through the command line.
We will provide more information and a webinar on using Source with Urbandeveloper with Source next year.
Summary of minor changes
- We have extended Scenario Input Sets within a Node or Link feature editor will show up. They now appear when there is a single Scenario Input Set, that isn't empty.
- Fixed an issue with Scenario Data Sources that failed to reload
- Fixed an issue with running Insight that occurred in a minor release of Source 5.10
- Improved the naming within Data Sources Overview to be consistent
- Extended the DoDoc plugin so it can be accessed through Scenario Input Sets and in the Export Summary.
- Fixed an issue with some tables, such as the Rainfall RUnoff editor, where the export would no longer import.
Community Plugin Changes
We have moved to .net 4.8.0 which requires Visual Studio 2019. We are planning on moving to .NET 6. The transition to .NET 6.0 won't be a quick process as some components we currently use will no longer be supported, however it does provide a potential pathway to running natively on Linux. Source can currently be run on Linux under Wine, but only natively on Windows.
Results and Configuration Changes
Some results have changed between Source 5.10 and Source 5.12. The eWater development team maintains a detailed system to track when results vary between different versions of Source.
The main result changes in the regression test suite were due to:
- modifying the order of storage outlet paths, and
- preventing negative storage volume in sub divisions.
Ordering Storage Outlet Paths
We found in a particular configuration of a complex model, the order Outlet paths were processed in a Storage could change the results. We now enforce consistent Outlet path processing to remove this inconsistency.
This has resulted in minor result differences in a number of models in our regression test suite.
Preventing negative storage volume in sub divisions
We found in a rare case that when a weir runs dry, it can cause negative volumes to occur in subdivisions of Storage routing.
The algorithm has been fixed to prevent this from occurring.
To test your project:
- Create a regression test in Source 5.10, see 5.10 Regression testing
- Run it in Source 5.12 to test for any result changes, see 5.12 Regression testing
