Smoke-control and fire-safety engineering: demonstrating the life safety of buildings through FDS and CFD simulation.
Whether you are designing a public-access building, a high-rise, a car park or an atrium, or you need to justify a solution before the safety commission, we can help. EOLIOS sets out to answer every question raised by the spread of smoke and heat in the event of a fire.
Our services rely on FDS (Fire Dynamics Simulator) and CFD simulation to visualise smoke propagation, temperature, visibility and the effectiveness of smoke control in any zone. Our studies demonstrate the life safety of occupants and the regulatory compliance of your installations.
Visualise smoke propagation and validate life safety from the design stage.

At EOLIOS Ingénierie, we specialise in smoke-control and fire-safety engineering through FDS and CFD simulation. Based in France, with offices in London, Milan, Munich, Madrid, Warsaw, Casablanca and the USA, our firm supports project owners, architects and inspection bodies in demonstrating the safety of public-access buildings, high-rises, car parks and atriums.
FDS (Fire Dynamics Simulator) simulation makes it possible to visualise and analyse smoke and heat propagation, visibility, temperature and toxicity with precision: keeping a low layer usable, the effectiveness of natural or mechanical smoke control, and compliance with the technical instructions (IT 246, IT 263). Coupled with evacuation modelling, it compares the time to reach safety with the development of the fire.
From theatres to car parks, from atriums to healthcare facilities, every study is carried out by our doctor-engineers with a clear, actionable deliverable for the safety commission — to guarantee the life safety and compliance of your buildings, in France and internationally.
Smoke-control studies rely on the expertise of a team of doctor-engineers in fluid mechanics, recognised in their discipline. Specialists in FDS simulation and CFD, our engineers support project owners, architects and inspection bodies at every stage of a project: design, life-safety demonstration, commission review or expert assessment.
Originally founded in France, EOLIOS Ingénierie is today a benchmark consultancy in fire-safety engineering, in Europe and worldwide. Present in Paris, London, Milan, Munich, Madrid, Warsaw, Casablanca and the United States, we work on all kinds of buildings — combining sharp scientific expertise, high-performance computing tools and a mastery of fire regulations.
