Build and Install

• To clone FENGSim:

  git clone https://github.com/FENGSim/FENGSim.git
  

• To clone CFD:

  cd FENGSim/toolkit
  git clone https://github.com/FENGSim/CFD.git
  

• To install OpenFOAM:

  cd FENGSim/toolkit/CFD/openfoam
  ./install
  

OpenFOAM comprises two core repositories: OpenFOAM-dev and ThirdParty-dev. Note that the suffix -dev can be replaced with a specific version number, such as OpenFOAM-12 and ThirdParty-12. It is required to place both repositories (e.g., OpenFOAM-dev and ThirdParty-dev) in the same parent directory, as they are compiled together during the build process.

Many examples (preprocessing files) can be found in FENGSim/toolkit/CFD/openfoam/OpenFOAM-dev/test and FENGSim/toolkit/CFD/openfoam/OpenFOAM-dev/tutorials. Application examples (secondary development source codes) can be found in FENGSim/toolkit/CFD/openfoam/OpenFOAM-dev/applications.

The shell script wmake is the compilation tool for OpenFOAM. Scripts such as Allwmake utilize wmake to automate the build process.

To set environmental variables for executing binaries or linking libraries:

cd FENGSim/toolkit/CFD/openfoam
source OpenFOAM-dev/etc/bashrc
echo $FOAM_INST_DIR

To run an application exmaple that creates a directory:

cd FENGSim/starter/openfoam/mkdir
wmake
./Test-mkdir
