Evacuation Modeling Tools

STEPS - Mott MacDonald

STEPS is a program developed by Mott MacDonald for simulating pedestrian dynamics in a 3D environment under both emergency and normal conditions. To model an evacuation scenario, users select the FDS model to import the geometry and smoke data files, set the population parameters, and run the simulation. FDS Isosurfaces, Slices and 3D smoke can be displayed while the evacuation is underway. Users can also activate the option to alter pedestrian walking speeds based on visibility conditions according to the Jin-Yamada experimental data (or other data specified by the user).

Pathfinder - Thunderhead Engineering

Pathfinder is an agent based emergency egress simulator that includes an integrated user interface and animated 3D results. Pathfinder allows you to evaluate evacuation models more quickly and produce more realistic graphics than with other simulators. Key Features: Import 2D/3D CAD, PyroSim and FDS files, Continuous Movement Mesh, Multiple Simulation Modes (SFPE and Steering), Flexible Exit and Intermediate Movement Goals, Elevators, Stairways, Escalators, Moving Walkways, Ramps, Custom Occupant Populations, Turnstiles and Other Flow Constraints, High-quality 3D Visualization and Powerful Data Evaluation Tools.

Fire-Structural Interaction

FDS2FTMI - Julio Cesar Silva

FDS2FTMI is an automated code to do one-way coupling between FDS and FEM using the Fire-ThermoMechanical Interface (FTMI). This interface model uses the Adiabatic Surface Temperature concept to establish an interface between FDS and FEM codes. The procedure recreates the net heat flux evaluated in FDS, in the FEM environment by transferring Adiabatic Surface Temperature and the convective heat transfer coefficient from FDS results and adopting the wall temperature provided by the FEM code at each time step. This heat flux can be calculated by FEM over the elements faces and applied into each node of the exposed surface. FDS2FTMI is a code created to perform these tasks in an automated way, allowing the simulation of the behavior of entire structures, discretized with shell and/or solid elements, exposed to fire conditions.

Miscellaneous

FIM, Fire Integral Model - Ilya Karkin

In solving problems of fire safety, it is often necessary to perform a series of calculations with different initial conditions. In such cases using FDS becomes difficult because each calculation requires significant time and computing resources. In practice, this limits the number of scenarios under consideration, which may affect the quality of the study. FIM implements calculation of the dynamics of fire hazards by using a one-zone integral model, using the input file format of FDS. If the the building topology corresponds to the definition of the integral model, the FIM significantly speeds estimation, before launching into a lengthy calculation FDS. There is no need to create a new model of the building in any other format - the program reads the source FDS file, calculates the dynamics of the fire hazards and generates output files similar to FDS, which can be analyzed in programs like Smokeview.

FDS/Smokeview Training

FDS Distance Education Supervised Project - FireModel Inc, Ontario, Canada

The School of Fire Protection at Seneca College has offered a distance education course on FDS since 2003. This was created and run by David McGill, who has since retired from Seneca. The course is still being offered through his consulting business, Firemodel Inc.

The Supervised Project is for fire protection practitioners with an understanding of fire dynamics. The course comprises a number of discrete topics that isolate the features that must be considered when simulating fires with FDS. There are small exercises to illustrate the important feature of each topic. In addition, you will gradually incorporate each feature into a more complicated model of your own choosing. A 6-month license for PyroSim is provided. This is a self-paced non-credit course.

Syntax Highlighting

FDS-VIM-Syntax - A. Louie

VIM syntax highlighting for FDS input files. To use fds.vim, create a runtime directory to store the syntax file.

$ cd ~
$ mkdir .vim
$ cd .vim
$ mkdir syntax

Now copy fds.vim into the ~/.vim/syntax/ directory.

$ cp ~/Downloads/fds.vim ~/.vim/syntax/.

Next, make sure your .vimrc file has syntax highlighting turned on and that it points to the fds.vim file.

$ vi .vimrc
syntax on
if has("autocmd")
  au BufNewFile,BufRead *.fds set filetype=fds
endif

Log out and log back in to have new setting take effect.

SublimeFDS - R. McDermott

Sublime Text syntax highlighting for FDS input files. This syntax is based on the Sublime Fortran Namelist syntax. The main differences are that namelist groups and parameters must be valid FDS inputs to be highlighted and there is better treatment of comments.
