A simulation of one building usually involves 4 to 20 scenarios. We run them in parallel in our own server room, alongside the other buildings in progress, so nothing waits for a free machine.
We build models in our own software, WizFDS, and simulations are handled by a dedicated CFD department. In 2025 alone we carried out analyses for more than 700 projects. For urgent deadlines the report is ready in as little as 5 working days.
Fire CFD simulations are most often used to verify the performance of the smoke control ventilation system. We carry them out for buildings of many kinds:
We have repeatedly validated our simulations during hot smoke tests: in most cases the flows observed at commissioning matched the model.
A smoke control CFD analysis answers one question: will the designed system maintain conditions for evacuation and firefighting for the required time? We run the fire simulation in FDS for the scenarios set out in the building's fire strategy and compare the results with visibility, temperature and flow criteria.
We use the results in fire scenarios and fire engineering expertise, and confirm them with hot smoke tests at commissioning.
Years of experience led us to develop dedicated software that speeds up building CFD simulations. WizFDS is open-source software (GNU GPL v3 licence), fully funded by F&K and made available to the international community.
Day to day we compute in FDS, which models, among other things, the transport of heat and combustion products, heat transfer by radiation and convection, pyrolysis and flame spread, as well as the activation of sprinklers and smoke or heat detectors and the interaction of water droplets with the flame. For airflow and comfort analyses we use Ansys Fluent, and for evacuation Pathfinder.

FAQ
A CFD (Computational Fluid Dynamics) simulation is a numerical model of smoke and heat movement in a building. The software divides the space into millions of cells and calculates how temperature, visibility and gas concentrations change during the fire. It shows whether the smoke control system will maintain conditions for evacuation and firefighting.
When the performance of smoke control or fire ventilation cannot be demonstrated by simple calculations: in car parks with jet fan ventilation, atria, shopping centres, tunnels and metro stations, and for alternative (fire engineered) solutions, which in Poland are agreed with the Regional Fire Service Headquarters (KW PSP).
A simulation that checks whether the designed smoke control system keeps escape routes clear of smoke and sufficiently cool for the required time. The output is visibility, temperature and velocity fields, compared against the agreed acceptance criteria.
We have our own server room with 300 multi-threaded processors and run many buildings on it in parallel, so projects do not wait in a queue. We build models in our own software, WizFDS, and simulations are handled by a dedicated CFD department. For urgent deadlines the report is ready in as little as 5 working days.
It depends on the size of the building, the number of fire scenarios and the required mesh resolution. We price each project individually once we have the plans and a description of the ventilation system.
Yes. We work as a CFD subcontractor for design practices, engineering consultancies and ventilation suppliers, also under their brand. We have delivered projects in Greece, Cyprus, Sweden, the United Kingdom, Romania, Oman, Saudi Arabia, Egypt and Mexico, among others.
