iZone
One-zone fire simulation with configurable ventilation, fire loads, and structural timber contribution.
Main use cases
- Natural-fire exposure for compartment checks
- Ventilation and fire-load sensitivity studies
- Assessment of combustible structural timber
Main features
Compartment builder
Define room dimensions, wall openings, and layered wall, ceiling, and floor constructions with a 3D preview.
Fire and combustion models
Select EN 1991-1-2, UK National Annex, or manual fire-load inputs and account for oxygen-limited burning or external flaming.
Coupled simulation
Follow gas temperature, oxygen, heat release, boundary heat transfer, and structural timber charring through time.
Supported inputs
- Room width, length, and height
- Opening sizes and positions
- Layered wall, ceiling, and floor properties
- Fire-load and fire-growth model
- Combustion and simulation settings
Results generated
- Standard-fire equivalent time
- Gas temperature and oxygen concentration
- Internal, external, and total heat-release rate
- Burned energy
- Charring depth of combustible parts
