blastFoam is a solver for multi-phase compressible flow with application to high-explosive detonation, explosive safety and airblast, as well as general compressible flows. blastFoam is developed by Synthetik Applied Technologies.
This offering is not approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software via www.openfoam.com, and owner of the OPENFOAM
and OpenCFD trade marks.
blastFoam is a solver for multi-component compressible flow with application to high-explosive detonation, explosive safety and airblast, as well as general high-speed compressible flows. The blastFoam solver uses OpenFOAM technology, and is in no way approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software via www.openfoam.com, and owner of the OPENFOAM and OpenCFD trade marks (see Disclaimer above).
Several validation and tutorial cases are included in the repository, and are documented in the blastFoam User Guide.
-
Install OpenFOAM from source or via binary/package installation from here (blastFoam works with OF version 7).
-
Create the OpenFOAM directory
mkdir -p $HOME/OpenFOAM- Go to the $HOME/OpenFOAM directory
cd $HOME/OpenFOAM- Clone the blastFoam repository
git clone https://github.com/synthetik-technologies/blastfoam- Go to the blastfoam directory
cd $HOME/OpenFOAM/blastfoam- Append the etc/bashrc to your .bashrc file
echo "source $HOME/OpenFOAM/blastfoam/etc/bashrc" >> $HOME/.bashrc- Load and set the bash environment to compile blastFoam
source $HOME/.bashrc- Compile blastFoam (for parallel use "-j")
./Allwmake- Test your installation by running the tutorial and validation cases
