Lecture and exercise notes on fire simulations

Webpage of the build script

Local Development

Note: The following explicit commands are for bash / zsh on Linux / MacOS.

1. Clone repository

git clone https://github.com/FireDynamics/LectureFireSimulation.git

2. Inside the repository, setup a virtual environment for Python

python -m venv .venv

3. Activate the virtual environment

source .venv/bin/activate

Requirements for different systems, see link:

Platform	Shell	Command to activate virtual environment
POSIX	bash/zsh	$ source /bin/activate
	fish	$ source /bin/activate.fish
	csh/tcsh	$ source /bin/activate.csh
	PowerShell Core	$ /bin/Activate.ps1
Windows	cmd.exe	C:> \Scripts\activate.bat
	PowerShell	PS C:> \Scripts\Activate.ps1

Note: In Windows PowerShell there is a restriction to run scripts. If the Execution Policy is not changed it will raise a message like "cannot be loaded because the execution of scripts is disabled on this system". One can allow the execution of scripts for the active PowerShell session by Set-ExecutionPolicy Unrestricted -Scope Process, see link.

4. Install the required Python packages, needed only once

pip install -r requirements.txt

5. Launch JupyterLab

jupyter-lab

6. Do some editing. The contents of the book are stored in the content folder.

7. Build a local version of the book

cd book
jupyter-book build .

Note: Some notebooks are capable to turn the output of matplotlib figures on and off based on the environment variable JB_NOSHOW. It should be set (to any value) to prevent the rendering of dublicate figures, e.g.:

cd book
JB_NOSHOW=1 jupyter-book build .

8. If the build is sucessful, the location of the build book is stated. You can open it with a browser.

Data Repository

The simulation input files as well as the resulting simulation data is stored in the data folder.

Execution of Simulations

In all data subfolders, FDS input files as well as a run script case_run.sh is located. You may have to adjust the execution command of FDS at the top of the script.

Download Precomputed Data

The case_download.sh script inside the individual data subfolders can be used to download precomputed data.

Contribution
