Evacuation simulation

Fenix+ does not need to divide a building into separate sections to calculate evacuation time. People can move in all directions. You only need to indicate objects for people to go around.

This approach matches the building information modelling (BIM) concept and takes evacuation simulation for buildings with complex shapes to the next level.

People movement simulation model includes several components

  • People use the shortest way to exit
  • People avoid objects in their way
  • People evade collisions with each other
  • Evacuation routes are selected with regard to less crowded exits
  • You can choose people groups, which are allowed to use exits
  • You can specify for people random routes to exits

In Fenix+ you can also create custom people groups with unique physical and movement characteristics

Fire dynamics simulation

Fire dynamics simulation is done in FDS software developed by the National Institute of Standards and Technology (NIST).

Fenix+ automatically prepares a scene for FDS. The software determines the number and size of cells in a given area. It divides the area into cells and makes necessary adjustments to multiple calculation areas in the scene.

Fenix+ is not just a pre-processor for Fire Dynamics Simulator. Before sending the scene to FDS, you can work with real-world objects such as walls, doors, and windows.


Objects you create in the scene are converted into objects suitable for FDS.

Fenix+ implements most FDS features. To learn more, please refer to the technical user’s manual.

Simulation results analysis

Fenix+ lets you analyze simulation results as calculated values and visualizations:

  • Dangerous factors of fire hazards
  • Evacuation time for every registering device
  • Evacuation flow density maps

With Fenix+, you can compare evacuation time for every registering device with its blocking time. All values are updated automatically so that you always get up-to-date information.


Unique approach to project management

Fenix+ 3 ensures flexibility when creating and editing fire scenarios.

Each scenario consists of several components: geometry, evacuation, and fire. You can easily combine them in various scenarios.

You do not need to always create a new model of building − just use existing scenarios with minor changes.


Save time and effort on engineering

With digital approach and modeling of physical processes in a building, you will avoid many mistakes and make a fire safety analysis.

Fenix + is based on modern visualization technologies, parallel computing, and algorithms to streamline your processes and tasks.

Thanks to integration of Fenix+ with Fenix Server, you can simulate fire dynamics on a greater scale.
