FLACS, with over 40 years of extensive testing and validation, benefits from Gexcon's continuous development of new physical models, informed by mid to large-scale experiments. 

The software’s validation group meticulously ensures that various FLACS modules align with real-world experimental data through an automated validation framework.

Data from 1,000+ physical experiments and real incidents have been categorised and stored in Gexcon’s validation database which is continuously expanded with new internal and external test data.

Be part of the FLACS User Group (FLUG) where users obtain a valuable opportunity to engage in a dynamic exchange of knowledge and experiences. 

It facilitates collaboration, enabling members to share best practices, discuss challenges, and discover innovative solutions. 

This community not only enhances individual expertise but also contributes to the collective advancement in the field of safety modelling.

FLACS is a CFD tool specifically developed for process safety applications, particularly in addressing complex hazard scenarios common in process industries. These scenarios often involve fluid dynamics in large-scale, three-dimensional settings.

FLACS expertly handles situations such as the dispersion of flammable or toxic gases, explosions involving gas or dust, the propagation of blasts and shockwaves, and the dynamics of pool and jet fires. Its development began in 1980 at the Christian Michelsen Institute's Department of Science and Technology in Norway.

The utility of FLACS in conducting consequence assessments goes beyond specific industries, applying universally to safety design and optimisation. Its applications are diverse, covering emerging renewable energy sectors, including hydrogen energy utilisation, carbon dioxide transport in carbon capture and storage (CCS) systems, and the production and application of various biofuels, among many others.

FLACS enables the analysis of the following scenarios (among others):

• Probabilistic fire and explosion
• Blast propagation
• Worst-case or realistic worst-case explosion
• Mitigation and layout optimisation for fires and explosions, as well as toxic and flammable releases.
• Dust explosion risk assessments
• Cryogenic releases
• Exhaust fume and flare design
• Toxic/flammable gas dispersion
• Gas, fire, and smoke detector layout optimisation
• Helideck or crane siting
• Mechanical ventilation optimisation and HVAC system design
• Smoke modelling and escape route impairment
• Quantitative fire and explosion risk assessment

FLACS can be used for a wide range of studies including (but not limited to):

• In-depth analysis of the consequence of releases, dispersions, fires and explosions with particular consideration to the importance of geometries and terrains
• Regulatory compliance (DSEAR, ATEX, NFPA, etc.)​
• Detailed facility siting
• Detailed fire and explosion mitigation measures design and layout optimisation
• Detailed fire and gas detector layout optimisation
• Assessing the impact of explosions towards blast walls and explosion relief panels
• Optimising test conditions when evaluating PFP equipment reliability
• Probabilistic fire and explosion risk analysis
• Worst-case gas and dust explosion analysis
• Detailed incident reconstruction for incident investigation
• Other studies that require in-depth consequence evaluation

The result in FLACS is presented in (among others) flow rates and release duration, flame dimensions and radiation levels, overpressure levels and gas concentrations, which are often a function of distance or X, Y location relative to its release coordinate.

The results from FLACS are presented in various formats, including numerical values, graphs, contours, 2D plot and 3D plot. Various export formats are available to accommodate different needs, including Excel sheets (.xlsx), word documents, and shape files for the export of consequence contours.

FLACS provides a range of flexible licensing options, such as standalone, network, and cloud licensing, available for different duration periods.
