5.6 - Beta Release (February 2021)

The changes in this beta will be available in the next Source production release, due out at the end of June 2021.

Improvements in this release include:

• Calibration using Parallel runs within Source, 
• Hot Start Rainfall Runoff Models,
• Improvements to the Data Sources Overview,
• Ability to model individual components of distribution loss and
• a number of minor improvements.

Calibration using Parallel runs within Source

When using the Shuffled Complex Evolution optimisation function, you can now run multiple instances of Source to improve the speed of the calibration:

This can be run through the User interface or through the commandline.

Hot Start Rainfall Runoff Models

When running Rainfall-runoff models GR4J or Sacramento, you can now take a Snapshot of their internal state variables:

This can then be saved to a file and applied at the start of a model run:

This removes the need to do a warmup period for running rainfall-runoff models.

Ability to model individual components of distribution loss

You can now model 9 different individual components of Distribution Loss at a Supply Point.  This is on a new, optional, separate tab:

Data Sources Overview Improvements

The Data Sources Overview  on the Data Sources Toolbar now has

• Export to csv, 
• Number of usages,
• Column filtering and sorting, and
• a new Usages view of where the Data Sources are used in the model.

You can also Group By columns. e.g. This is grouped by the Water Feature Type:

Minor changes

• Auto export results now use the dimension Display Units,
• The Simulation log file has more content for Data Sources,
• New recorder on confluences:  Constrained Historical Order For Long Branch
• New Scenario creator Single Catchment Scenario Builder:

Plugin Developers

We have moved to .NET 4.8 and are looking at moving to the new .csproj format on our journey to .net core. Once we complete this, we will require plugin developers to upgrade to Visual Studio 2019.

Regression Testing

We have removed the tolerance in our regression tests, to allow for earlier identification of different machines or versions of operating systems giving different results. 

Regression test repository changes since the first Source 5.5:

Insight

To run Insight, you also need to install the 32bit version of Microsoft Visual C++ 2010 Redistributable Package.
This installer is for both 32bit machines and 64bit machines since the library we use is 32bit: Microsoft Visual C++ 2010 Redistributable Package (x86).
