Operating System
To run GasSim 2 you will need an IBM compatible PC or laptop with a Pentium 4 processor with a speed of at least 1GHz with 512MB RAM. GasSim2 was developed to operate under Windows XP Professional, with Service Pack 2. Other earlier versions of Windows may be compatible but this has not been tested. GasSim2 is not compatible with Windows NT.

Disk Space

Hard disk space for temporary files generated while running gas generation and emissions modules may vary from 10MBytes to 100MBytes or more depending on the complexity of the simulation. The AERMOD module within GasSim2 can easily generate 6GB of results files, so users should allow a minimum 10GB free disk space on their C drives. Some simulations may require more disk space than this. It is possible to select other network drives for AERMOD output.

Display Resolution

GasSim 2 runs at a screen resolution of 1024 x 768.

The current version of GasSim is Version 2.0. Contact the Golder Associates
