Combination of crowd simulation and smoke simulation

We now offer the combination of smoke simulation and crowd simulation! With IANUS Simulation we have a competent and professional partner who complements us perfectly.

Flue gas & clearance

Smoke and evacuation simulation complement each other and, when combined, can provide a one-stop solution for performanced-based assessment. In order to obtain simple and valid results, accu:rate and IANUS are now cooperating to offer everything from a single source.

Advantages of combining flue gas and clearance

Combining smoke gas and evacuation simulations is an effective measure for improving safety in buildings. Integrating these two simulations allows realistic scenarios to be created, enabling a more precise analysis of the effects of smoke development on the evacuation of people. Smoke gas simulation makes it possible to visualize smoke development within a building. Evacuation simulation can be used to depict the movements of people during evacuation in order to identify bottlenecks or potential evacuation problems at an early stage. By combining both simulations, it is possible to see at a glance whether people can leave the building in time.

This enables complete performance-based verification in accordance with DIN-18009 be conducted in the event of deviations from building regulations.

Flue gas simulation for determining ASET (IANUS)

With Dr. Susanne Kilian as Business Unit Manager for Building Technology, IANUS Simulation brings an international expert on board. Her many years of experience in the development and application of flue gas simulation models optimally strengthens our offering.

Clearance simulation for determining RSET (accu:rate)

crowd:it already offers RSET evaluations as standard. In addition, the heat map can be created and exported at the touch of a button. This greatly simplifies the comparison of available and required clearance time.

How does it work?

1. Crowd Safety in Fire Protection

To demonstrate crowd safety in the context of fire protection when deviations occur, so-called ASET–RSET comparisons can be used.

2. Flue gas simulation and Evacuation Time

For each area of the building, it is checked whether the available safe egress time is greater than the required egress time. These two times can be generated from different simulations: The available safe egress time is obtained from a flue gas simulation that determines the smoke-free layer; the required egress time is determined using crowd:it.

3. Difference Heatmap and DIN 18009

Overlaying the two simulation results produces a so-called difference heatmap, which shows at a glance whether there are areas within the building that cannot be evacuated in time.

This procedure is also described in the framework standard DIN 18009 and is an internationally recognized performance-based verification method.
