What is BRANZFIRE?

BRANZFIRE is a zone model including flame spread options on walls and ceilings and is used to calculate the time dependent distribution of smoke, fire gases and heat throughout a collection of connected compartments during a fire. In BRANZFIRE, each compartment is divided into two layers. The modelling equations used in BRANZFIRE take the mathematical form of an initial value problem for a system of ordinary differential equations (ODE). These equations are derived using the conservation of mass, the conservation of energy, the ideal gas law and relations for density and internal energy. These equations predict as functions of time quantities such as pressure, layer heights and temperatures given the accumulation of mass and enthalpy in each of the two layers. The BRANZFIRE model then solves a set of ODEs to compute the environment in each compartment and a collection of algorithms to compute the mass and enthalpy source terms. The model incorporates the evolution of species, such as carbon monoxide, which are important to the safety of individuals subjected to a fire environment.

What type of computer do I need?

BRANZFIRE requires a PC running Windows 95, 98, 2000, NT, ME, XP or Vista. Pentium II CPU or faster recommended. Since BRANZFIRE simulations are computationally intensive, use the fastest processor you can afford.

Can I run BRANZFIRE on a MacIntosh?

We have not been able to successfully install the software on a MacIntosh running virtual PC. Feel free to try and let us know if you succeed.

The trial period has expired, can I get it extended?

The current version is not time-limited. Please upgrade your installation.

I have upgraded to a newer version of BRANZFIRE. How do I find out what the changes are?

From version 2002.7 onward, the version release history can be viewed from the help menu within the program.

If I install a newer version, will I lose my current licensing information?

The current version does not require licensing. Please upgrade.

The program freezes up when I try to access a T-squared fire in the fire database - what can I do?

Please upgrade to the current version.
