Install BARAM, NextFOAM, OpenMPI

  • OpenMPI is installed in the /opt/openmpi-4.0.5 with --prefix option at configure command
sudo apt-get -y update 
sudo apt-get -y install build-essential flex zlib1g-dev libgmp-dev libmpfr-dev
wget https://download.open-mpi.org/release/open-mpi/v4.0/openmpi-4.0.5.tar.gz 
tar zxf openmpi-4.0.5.tar.gz 
rm openmpi-4.0.5.tar.gz 
cd openmpi-4.0.5 
./configure --prefix=/opt/openmpi-4.0.5 
make -j all 
sudo make install 
echo 'export PATH=/opt/openmpi-4.0.5/bin:$PATH' | sudo tee -a /etc/bash.bashrc
  • Install required packages for GUI
sudo apt install -y  qtbase5-dev
sudo apt-get install -y '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev texinfo
  • Install BARAM using python virtual environment
sudo apt install -y  qtbase5-dev
pip install --upgrade pip
cd /opt
sudo git clone https://github.com/nextfoam/baram.git
cd baram
sudo apt-get install python3.9-venv
source ./venv/bin/activate
sudo pip install --ignore-installed -r requirements.txt
sudo pip install https://d3c6e16xufx1gb.cloudfront.net/wheels/PySide6_QtAds-4.2.1.2.dev0-cp38-abi3-linux_x86_64.whl
sudo pip install https://d3c6e16xufx1gb.cloudfront.net/wheels/pyqtgraph-0.13.5-py3-none-any.whl
  • Copy NextFOAM solver executables
  • Download the solver executables and uncompress it to the top directory of download source code
  • In this guide, /opt/baram is the top directory.

/opt/baram

  • You can download using wget or curl 

wget https://d3c6e16xufx1gb.cloudfront.net/solvers_linux_25.1.0_20250131.tar.xz


curl -L https://d3c6e16xufx1gb.cloudfront.net/solvers_linux_25.1.0_20250131.tar.xz -o solvers_linux_25.1.0_20250131.tar.xz

(Option) Build NextFOAM-2501

  • Instead of downloading the solver excutables, you can build the NextFOAM-2501
  • After build the NextFOAM-2501 solver, copy compiled solvers and libraries to /opt/baram/solvers/openfoam
export BARAM_DIR="/opt/baram"

sudo mkdir -p $BARAM_DIR/solvers/openfoam
sudo cp -a $WM_PROJECT_DIR/platforms/linux64GccDPInt32Opt/bin $BARAM_DIR/solvers/openfoam/
sudo cp -a $WM_PROJECT_DIR/platforms/linux64GccDPInt32Opt/lib $BARAM_DIR/solvers/openfoam/

  • Compile Daemonizer and resource
cd /opt/baram
sudo gcc -o solvers/openfoam/bin/baramd misc/baramd.c
sudo python3 convertUi.py
  • Run baramMesh or baramFlow

. baramMesh.sh
. barmaFlow.sh
