FLACS review
Specialized CFD modeling for industrial hazards, with desktop tools and optional cloud HPC execution.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FLACS is Gexcon’s computational-fluid-dynamics software for engineers and safety teams assessing industrial hazards and their consequences. Its scope includes gas dispersion and accumulation, vapour-cloud and confined explosions, jet and pool fires, ventilation, fire-and-gas detector layout, and facility siting. The product is relevant to process safety, risk management, regulatory submissions, incident investigation, and quantitative risk analysis across sectors such as oil and gas, chemicals, and energy. It is a focused simulation choice rather than a general-purpose modeling suite.
A notable strength is the range of connected hazard studies within one workflow. Teams can manage multiple scenarios and edit them in bulk, while the Python API supports scripted and batch workflows. Flowvis provides result visualization and analysis. Desktop preprocessing, simulation, and visualization tools pair with FLACS Cloud for cloud HPC execution; access to FLACS Cloud requires a FLACS-CFD license. RISKCURVES is the listed integration, which may matter to organizations already using that software. The product is available for Windows and Linux, with API access and both desktop and cloud deployment options.
Commercial access is handled through Gexcon’s product specialist team rather than published license prices, so buyers should expect to discuss requirements directly with sales. Support channels include email and documentation. FLACS is a fit for mid-market and enterprise organizations whose work centers on industrial fire, gas, explosion, ventilation, or facility-layout risk. Teams seeking those specific capabilities, including batch scenario work or optional cloud execution, should consider it; buyers looking for broad, general-purpose simulation software may be better served by an alternative with a wider modeling focus.
FLACS pros and cons
- Where it wins
- Models dispersion, explosions, fires, ventilation and detector layouts
- Python API supports scripted and batch scenario workflows
- Optional FLACS Cloud execution uses scalable HPC infrastructure
- Where it doesn't
- Specialized around industrial hazard and consequence modeling
- FLACS Cloud requires a FLACS-CFD license
- Commercial pricing is handled through sales enquiries
