The main methods for customising Source are through /wiki/spaces/SD47/pages/54165824, /wiki/spaces/SD47/pages/54165763 and using the /wiki/spaces/SD47/pages/54165607.

/wiki/spaces/SD47/pages/54165763 are a powerful math and logic language built into Source (similar to Excel formula)
/wiki/spaces/SD47/pages/54165824 are Open ended system for changing the algorithms, user interfaces or the operation of Source
External Scripting with the /wiki/spaces/SD47/pages/54165607 allows you to do Batch runs, optimisation, and links to other systems.

Source is built upon TIME, a general purpose modelling system. TIME is a software framework for developing eco-hydrological models based upon the Microsoft .NET framework. It is designed to support the creation, testing and end-user delivery of environmental simulation models.

Supports the management, manipulation and presentation of a variety of data types, as well as support for testing, integrating and calibrating simulation models.

TIME Underpins a range of spatial and temporal modelling systems including a number of toolkit models (www.toolkit.net.au)
