MFIRE is a software program for modeling fire and contaminant spread in underground mines.
This is an updated version of the DOS-based MFIRE program originally developed by the U.S. Bureau of Mines. It has been completely rewritten in C++ and packaged into a dynamic link library (DLL). The benefits of this restructuring include:
Ease of future maintainability and improvement using object-oriented C++.
Ventilation network data is obtained via common memory instead of the standard MFIRE data output files.
The MFIRE DLL can be easily used by other programs.In addition, MFIRE has been restructured to run as a discrete event simulation and now allows user control of execution time. A simple graphical user interface (GUI) is provided to demonstrate the functions available through the new MFIRE DLL. Extensive documentation on the use and structure of the MFIRE DLL is provided in the built-in help of the simple GUI.
**Installation Instructions:**
Download the ZIP archive, unpack into a temporary folder and run **MFire Setup.exe**.
Source files for both the simple graphical user interface and the MFIRE library are also available for download.**New to version 4.0**
Added T-Squared fire algorithm
Including properties of the fire (Tlead, Tmax, Tsteady, Tdecay, Qmax, FumeProConstant)
Added Heat Release Rate Curve input lines to config file (see example files)
Added SmokeRollback calculations and indicator
Including Properties: HasSmokeRollback, LengthOfRollback
Added to config file the ability to define a FireType (allows setting which type of fire calculation: Original, HRR Curve, T-Squared)
Added ChangeFire event
Added x, y coordinates to junctions (and corresponding config files)
Updated text config file to handle comments (see new example config files)
BUG FIX: Fixed a bug which causes out of boundary index compiling error when TransientState is set to 1
BUG FIX: Englarged the size of arrays from +10 to +100 to let a case run through.
