eWater is pleased to announce the latest Production Release of Source version 4.11. Version 4.11 contains .............................
Highlights of Source Version 4.11 include:
...
At the moment you need to have a single single outlet for all of the sub-catchments you are combining. We will relax this restriction in future versions.
...
You can select a single node and combine all of the catchments upstream of it.
Blackwater plugin
Initial conditions can now be specified as varying according to elevation

Calibration tool
The calibration tool has undergone significant enhancements. It has been changed from a flow calibration tool to a generic calibration tool. You can now specify any recordable output (including functions) to be used as part of the objective function in the calibration wizard. The independent variable can now be a Data Source, rather than a separately loaded text file.
We still have more work to do in allowing any parameters to be modified. We have enabled users to calibrate constituents as a first step.
Environmental Flows with NetLP
The new Environmental Flow node and Environmental Flow Manager now work with NetLP ordering. To determine the "marginal" difference in orders that are required by the Environmental Flow Node, NetLP determines probable flows throughout the system prior to determining environmental flow orders. The model does order phase twice - firstly Expected Flows without initiating new Environmental Flow orders are determined. These flows are then provided to the environmental Flow Nodes to perform their ordering calculations. NetLP is then given the environmental flow demands as well as all of the other demands. The system then resolves.
Improved generation of orders at Storages and Weirs
Allow the user to specify a factor to smooth the rate at which downstream storages orders water from upstream.
Infinite loops resolved
We have modified Off Allocation and Environmental Flow Manager distribution logic to remove infinite loops which could occur in some models.
The changes in this beta will be available in the 4.11 production release, due at the end of December 2019.
The most significant change for this release are the improvements to the calibration tool.

Chart changes
We have resolved a number of issues identified with charts and the mass balance tool since their redevelopment.
Chart aggregation can now ignore null values. This allows for the aggregation of seasonal data to an annual time series. e.g. you can now generate a series of the total summer inflows each year.
...
Off allocation had an option called "Equalise Shares", which wasn't used by any of the jurisdictions, and has now been removed.
Insight changes
Insight now produces a file which is a cache of model run results. This means that when you run an insight optimisation and then decide to increase the number of generations of the optimisation, you can continue the extended optimisation from the end of the previous optimisation.
This also means you can stop an insight run and restart it without wasting a large amount of time.
Minor changes
- Improved generation of orders at Storages and Weirs. Source now allows the user to specify a factor to smooth the rate at which downstream storages orders water from upstream.

Plugin Developers
ScenarioRunFinalise now happens on all plugins. If there was an exception in one plugin, it previously wouldn't run ScenarioRunFinalise for the remaining plugins when there were multiple plugins.
We are currently on .net 4.6.2, which hasn't changed from Source 4.7. We are planning on moving to C# 7, Visual Studio 2019 and .NET 4.8.0 soon, so you will need to make sure you have updated Visual Studio to continue developing plugins in the beta versions. We also intend to move to .NET 5 in 2020. .NET 5.
