3D Compartments

A fire model can be considered as divided into several zones or compartments. FRI3D makes it easy to model individual compartments in 3D.

Each compartment is representative of a physical geographical area and several scenarios occuring in the compartment or across compartments of interest can be simulated in FRI3D. The compartment inspector has got the list of compartments , so they should be created or loaded in the compartment inspector before their appopriate 3D components can be constructed.

Any analysis is started by either creating a new compartment or loading an existing compartment if a database is already loaded. By default when FRI3D is started an empty database is created with no compartments.

However if an existing database loaded has compartments already they are listed in the combo box as indicated by the following figure. The Compartment/Zone Inspector is detailed in the section !Zone Inspector.

The first step in a fire analysis is to load an existing compartment or create a new compartment.

Create a Compartment/Zone#

To create a new Compartment/Zone hover the mouse in the compartment inspector .

`COMPARTMENTS -> New Zone`

Load Compartments/Zone#

A specific compartment of interest can by using the top level combo menu or the dropdown list. If a new compartment has been created as indicated in the previous step that compartment is automatically loaded.

However if an existing compartment needs to be loaded into the scene, the combo box is used as indicated below.

The loaded compartment if comprised of 3d Geometry is displayed in the 3D window.

Switch Compartments/Zone#

The compartment of interest can be switched to either a related compartment which participates in the scenario or to a completely different compartment of interest to model.

Floor plan#

Its possible to import a 2D drawing and display it in the floor of the 3D viewer. This makes it possible to import a floor plan, which can facilitate the modeling process and its verification.

A pdf file or an image of a floor plan can be included as part of the compartment being modeled.

CAD Import#

FRI3D can import previously modeled geometry by a CAD modeler. Currently only import of polygonal models in the following formats are supported

But work is in progress to be able to import STEP and IFC files in Boundary representation (B-Rep) format.
