RR779 - Review of FLACS version 9.0: Dispersion modelling capabilities

FLame ACceleration Simulator (FLACS) is a commercial Computational Fluid Dynamics (CFD) code developed and marketed by Global Explosion Consultants (GexCon), based in Bergen, Norway. The software has been developed to model the dispersion and combustion of flammable liquids, gases and dust clouds in open and bounded geometries.

The first version of FLACS, released in 1986, was developed by CMI (Christian Michelsen Research Institute). CMI continued the development of FLACS until 1992 at which time its development was passed to CMR (Christian Michelsen Research). GexCon was established in 1998 to manage the consultancy activities of CMR and in 2000 it took full responsibility for the development of FLACS. At present the company employs around 35 people, many of whom are involved in the development of the software. The present release of FLACS is Version 9.0, which forms the subject of the present review.
