Advanced software for modelling dense gas dispersion

Model development and verification

GASTAR has participated in major validation exercises, such as those of Hanna et al.1 and SMEDIS2. The comparative exercise of Hanna et al. showed GASTAR to be one of the best performers for the standard data sets in flat terrain; while in SMEDIS the model was able to simulate successfully data sets from a wide range of experiments, most featuring one or more of the complex effects of slopes, obstacles and aerosols.

User support

GASTAR is supplied with an in-depth user guide (see the User guides page) that details all user inputs and outputs and includes description of other utilities such as the pool uptake model, the Flash calculator, the X-Y plotter and the flammables plotter.

An annual maintenance contract provides support for users; this includes:

  • maintenance model upgrades,
  • use of the helpdesk by e-mail, phone, fax or post.

A range of training courses are offered by CERC. Please browse our Training pages for more details.
