...

You can now write your own custom log messages to help check model configuration and behaviour. Rightclick on the function and select "Add Custom Logs". You can then set up different levels of logs e.g. Info, Warning, Error or Fatal Error.  The user defines the message.  The result of the function determines the level of the log message:

Improved validation

There is a new Assurance rule for NetLP Convergence Failures that is a warning by default.

Water Users not using Account Sharing when assigning RA accounts is now an error by default. When a Water User is an account host in a Resource assessment System, the Water User should be set up to use Account sharing. This rule is now fatal by default, however, like any assurance rule, it can be turned off if this is the desired configuration.

New Community Plugins

Two new community plugins have been released:

  • SourcePlugin.AllocationAndUtilities – is a collection of small, common utilities to help in river modelling. Thanks to Tim Smith from NSW (Dept Industry – Water) for developing this plugin.
  • GR4H - a catchment water balance model that relates runoff to rainfall and evapotranspiration using hourly data. The model contains two stores and has four parameters.

Changes to Weirs

We have improved the process for converting weirs to storages and vice-versa. You can now Use Copy \ Paste with weirs in the schematic view, and Convert Storages to Weirs or Weirs to Storages.
