ForeFire

Refer to the Wiki for a more detailed guide on using ForeFire.

ForeFire is an open-source code for wildland fire spread models, developed and maintained by Université de Corse Pascal Paoli.

Access the demo simulator here.

It has been designed and runs on Unix systems. Three modules can be built with the source code.

The main binaries are

• An interpreter (executable)
• A shared library (with C/C++/Java and Fortran bindings)

1. Requirements

The requirements and ForeFire can be installed by running install-forefire.sh (Ubuntu or Debian distributions)

cd forefire

sudo sh install-forefire.sh

The program will be built in: ./bin/forefire

OR run the commands:

apt-get update

apt install build-essential -y

apt install libnetcdf-dev libnetcdf-cxx-legacy-dev -y

apt install cmake -y

To install

• The C++ compiler
• NetCDF Library and NetCDF-C++ legacy
• Cmake build tool

2. Build

2.1 Cmake

To build with cmake run the script

sh cmake-build.sh

To make the program executable from eveywhere (during the session) Add the bin folder to path

export PATH=$PATH:`pwd`/bin

If you want to change it permanently, paste

export PATH="</path/to/file>:$PATH"

at the end of your ~/.bashrc file. The file can be edited with

nano ~/.bashrc

for example

export PATH="/mnt/c/gitrepos/forefire/bin:$PATH"

2.2 Scons and Other build systems

More information on other build systems are available here

3. Running an example

An example for the region of aullene in south France is provided. The example contains 3 files

• fuels.ff
• aullene.ff
• landscape.nc:

Run the example with

cd firefront/examples/aullene/

../../bin/forefire -i aullene.ff

The simulation result will be outputed in JSON format

4. Running with python

Installing requirements

cd py3_tools
pip install -r requirements.txt

You can use the script coord_to_ff.py to run the simulation in a default location

python coord_to_ff.py

For running in a chosen location, the script accepts latitude and longitude in epsg:4326 projection as inputs. It reprojects the coordinates into epsg:32632 projection, used in aullene's landscape.

python coord_to_ff.py --lat 41.6 --lon 9.1

The GeoJSON of geometry type Polygon will be saved in the /examples/aullene folder

4. Building python Lib

The /swig folder contains and Sconstruct file for python bindings.

Requires numpy (and numpy.i), swig, and matplotlib for testing.

5. Building with Docker

A sample Dockerfile can allow to build a Docker image with

docker build . -t forefire

To run this image and interactively acces the continer use

docker run -it forefire bash
