The size of the systems you plan to simulate will determine the Computer Processing Power and RAM needed.
  • 586 class PC running Windows.
  • 256 Mb RAM available to GWIS.
  • Standard mouse.
  • Windows compatible graphics system.
  • Microsoft .NET version 1.1 or later installed.
  • 2400Mhz PC or better running XP Pro or Vista.
  • 2048 Mb DDR2-3 RAM available to GWIS.
  • 2D/3D 512Mb DDR3-4 Graphics Accelerator.
  • SATA-2 hard drive. Minimum 7200RPM.
  • We recommend a large CAD grade display.


CAD type simulation software like GWIS relies heavily on the Floating Point processing capability of a PC processor. This is determined by the number of Cores, Floating Point pipelines and processor speed(MHz). GWIS also likes lots of fast RAM with low latency to solve and draw large systems at great speed.


  • GWIS is built on Microsoft .NET and will thus be compatible with any Windows platform with .NET installed. Windows Vista already has .NET pre-installed.
  • GWIS 7 requires 256Mb RAM to install.
  • GWIS 7 requires a Windows screen resolution of at least 1024 x 768 pixels. We recommend a graphics resolution higher or equal to 1280 x 960.
  • GWIS 7 works on normal or wide aspect ratio screens.
  • If some of the GWIS panels do not appear on the right hand side of the screen, your graphics system is not 100% compatible with Windows . This can typically be found in low end on-board graphics solutions of some laptops. GWIS has been tested to be compatible with Nvidia & ATI graphics solutions.
