Source Versions

There are several versions of the Source software, all of which are available via the eWater Toolkit at toolkit.net.au. Source (public version) is freely available as soon as a free Toolkit account is created. Other versions, such as the betas or the Source version with full water sharing functionality, is restricted under certain licensing conditions.

System Requirements

Outlined below are the minimum recommended system requirements for installing Source. Note that software installation may require the assistance of a system administrator.

Minimum recommended requirements
  • Windows 7 (64-bit), Windows 10 is supported;
  • .NET Framework 4.6.2. If you do not have this, your computer will automatically download and install it (with a notification) after installing Source.
  • Two hard drives (one for the Operating system) and a 10,000 RPM hard drive with write caching or a solid state disk (SSD); and
  • 16GB RAM.
Screen / Resolution
  • Large fonts (Windows 7) / Custom Scaling greater than 100% (Windows 10) is not supported
  • Minimum screen resolution is 1920 x 1080

Up to 5GB of available space may be required, and maintaining a free hard disk space of at least 20GB is recommended.

For large models, 32GB of RAM is recommended, and a minimum of four cores.  For parallelisable models, the more cores the better. Run time is often tied to CPU, so the faster the CPU, the faster the runtimes.

If using Insight, you will also need the Microsoft Visual C++ 2010 Redistributable Package, 32-bit version (for both 32 and 64-bit machines): available here.

Note: Standard laptop drives are not recommended for optimum performance.
