Computational modelling and visualisation plays a key role in demonstrating fire engineered solutions, as it allows us to provide models of human behaviour, smoke ventilation and building reaction to elevated temperatures.

Computational fluid dynamics (CFD) are used to model the action of smoke and fire in a building optimising the specific locations of smoke control features such as smoke vents, fans and curtains. CFD allows the performance of the systems to be demonstrated visually within a three dimensional model of the building easing the understanding of the fire design to clients and approving authorities alike.

We use Exodus software to model evacuation strategies. It is capable of simulating evacuation scenarios in all types of buildings and combines people’s behaviour during a fire with a particular building type and layout. It produces real-time 3D simulations that can help identify natural bottlenecks and preferred exits and provides timings for different emergency scenarios.

We also use finite element analysis software to determine the behaviour of structural elements with varying fire loads. This is a key tool for checking that we have the protection we need in the areas we need it and that we are not needlessly protecting other parts of the building.
