MODELLING AND VISUALISATION
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 so that we can optimise the specific locations of smoke control features such as smoke vents, fans and curtains. CFD modelling provides a visual demonstration of the performance of the systems within a 3D model of the building, which is ideal for presenting to clients and approving authorities.
We use Exodus software to model evacuation strategies. It can simulate 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 a range of 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 protection is in place in the areas where it is needed, and that other parts of the building are not needlessly protected.
