KFX harnesses the power of computational fluid dynamics (CFD) to precisely model dispersion and fires in various scenarios.
Featuring computer-aided design (CAD) and topography import capabilities, KFX automatically converts geometries for seamless integration with the calculation models, ensuring an efficient and accurate representation of the impact of 3D geometries on the CFD simulations.
KFX provides comprehensive simulations of water-based fire mitigation techniques, including deluge, monitors, mist and water curtains, in complex systems and congested areas while accounting for weather effects.
Additionally, data from KFX can be used as input to USFOS, a simulation software dedicated to analyzing structural response to accidental loads resulting from fires and explosion.
Advanced dispersion and fire modelling using KFX can predict dispersion cloud behavior, helping to assess exposure to toxicity (for a toxic gas accidental release) or radiation (for a flammable gas accidental release) in open or enclosed areas.
KFX simulates ventilation, whether natural or forced, and can therefore help with layout optimization.
KFX has been continuously developed for over 40 years through joint industry projects (JIPs), including to support transport and storage of hydrogen and ammonia and for carbon capture and storage (CCS).

KFX/EXSIM is specifically developed for safety-related applications, addressing scenarios such as gas dispersion, fires, explosions, and other industrial challenges. Its features include the porosity technique, Lagrangian model for droplet releases, the ability to handle multiple simultaneous releases in a single model, and seamless integration with Finite Element software for structural response analysis.
Extensive usage and testing in numerous industry studies, both by DNV and external customers, have established KFX as a robust and stable simulator. Furthermore, the software has been developed in close collaboration with industry partners to best understand and address industrial needs efficiently and accurately. Notably, ongoing advancements include an advanced liquid CO2 release model that accounts for complex thermodynamics, two-phase releases, dry-ice formation and deposition, as well as obstacles, terrain, and wind conditions.
The competence behind KFX/EXSIM is the result of four decades of focused research, continuous development of fire simulation software, and consultancy work within turbulent flow and combustion, with funding from industry and the Research Council of Norway. Widely used in the industry, KFX/EXSIM is a leading CFD simulator for dispersion, fire, and explosion simulations. Extensive validation has been conducted, ensuring accurate results, and ongoing validation is based on experiments carried out in DNV Spadedam and with industry partners. KFX includes advanced Lagrangian models for fire mitigation and extinction using various water systems. It is also seamlessly interfaced with the KFX Usfos finite element structure response code, enabling non-linear dynamic structural response analysis. Additionally, KFX offers powerful CAD and topography import capabilities, allowing for automatic conversion of CAD geometries and easy handling of electronic maps. DNV's collaboration with industry partners on Joint Industry Projects (JIPs) focused on hydrogen, ammonia, and CO2 safety further enhances the software, with research results from these projects being integrated into KFX.
