OpenFOAM-TT

This project builds the core libOpenFOAM of the OpenFOAM project separately as a cmake project. The project is structured such that original sources are used, except for symbol-equivalent replacements provided by this project. The result shared library can be used with the original OpenFOAM driver by prepeding this project's build folder to the LD_LIBRARY_PATH.

libOpenFOAM

The core libOpenFOAM defines the basic abstractions for operations on sparse matrices used by the different abstract solvers. The structure of the project allows to explore different implementations of these matrices with a minimal setup and simple testing framework. In particular, we explore different offloading strategies with minimal impact on the users of the matrices.

Usage

Dependencies

sudo apt-get install -y build-essential libopenmpi-dev zlib1g-dev gnuplot gnuplot-x11 libxt-dev cmake flex ninja-build
sudo apt-get install -y libxml2-dev libhdf5-dev libavfilter-dev libtheora-dev libgl2ps-dev libx11-dev libqt5x11extras5-dev libglew-dev libutfcpp-dev 

Build

First, generate the original include paths of OpenFOAM and build the project.

cd 3rdParty/OpenFOAM-dev/

export WM_PROJECT_DIR=`pwd`
. ./etc/custom_bashrc

./wmake/wmakeLnIncludeAll
./Allwmake -j$(nproc)

cd ../../

Second, to build this project simply run:

mkdir build && cd build

cmake -G Ninja ..
ninja

Run (Cavity)

Generate the additional files once:

cd ${WM_PROJECT_DIR}/tutorials/incompressibleFluid/cavity
${FOAM_APPBIN}/blockMesh
cd ${WM_PROJECT_DIR}
cd ../../

Run the experiment:

LD_LIBRARY_PATH=$PWD/build:$LD_LIBRARY_PATH ./3rdParty/OpenFOAM-dev/bin/foamRun -case ./3rdParty/OpenFOAM-dev/tutorials/incompressibleFluid/cavity
