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 Ordered demand.

You can now model 10 individual components of Distribution Loss at a Supply Point.  This is on an optional, separate tab Complex Distribution Loss:

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 Urban Developer next year.

Summary of minor changes

  • We have extended Scenario Input Sets - now available from the Node or Link feature editor.  Associated Scenario Input Sets are visible in the feature editor when there is at least 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 storage routing link subdivisions.

Ordering Storage Outlet Paths

We found in a particular configuration of a complex model, the order in which 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 links. 
The algorithm has been fixed to prevent this from occurring.


To test your project:

  1. Create a regression test in Source 5.10, see 5.10 Regression testing
  2. Run it in Source 5.12 to test for any result changes, see 5.12 Regression testing
