 CFD Solvers with Automatic Meshing

  • Star CCM+ and CONVERGE  are also used as a popular CFD solver in many  automotive industries
  • They do not require a separate meshing platform. It directly generates dynamic grid adaptive mesh based on gradients of flow variables.
  • Siemens provides free access for universities  students and faculty to Simcentre  STAR-CCM+ 
  • Students can download Star CCM+ by clicking here: University: Star CCM+
  • COMSOL  has the Lattice Boltzmann method (LBM) in their solver
  • Students or faculty can contact to get a trial version
  • Students can download tutorials of CONVERGE 

Open source  CFD Solvers  (Free Software)

  • OpenFOAM  is  a  popular open-source CFD software for both academia and industries

 How to Install Open FOAM in Windows

 Install  Ubuntu for Programming Environment 

  • The first step to installing Open FOAM, your computer must have a programming environment to run the C++ libraries of Open FOAM
  • You can create it by installing Ubuntu either within Windows 10 or a separate operating system
  • Watch videos: click on the links
  • Then download and  install OpenFOAM after copying files in Ubuntu

 Download and Installation Guides 

  1. Download the Open-FOAM files as per the Ubuntu version in your system
  2. Start Bash on Ubuntu by typing bash in the search toolbar
  3. Click on the Desktop app Bash on Ubuntu on Windows

Bash on Ubuntu

  1. In the bash-terminal,
    • Copy “OpenFOAM-v2012-windows10.tgz ” from the Download folder to the local bash-environment by entering the following command: cp -ar /mnt/c/Users/<USER>/Downloads/OpenFOAM-v2012-windows10.tgz
    • You need to replace the string with your own user name while copying the file: here shown by the user pgh
    • The final dot (.)need  to specify the current location
  1. Untar the OpenFOAM installation file by running the following command
    sudo tar -xvzf  OpenFOAM-v2012-windows10.tgz -C /opt/
    sudo chown -R $USER /opt/OpenFOAM

    Enter your Linux password to allow the process to start. if tar is not installed in your Linux version, you have to install it using the command: sudo apt install tar

  2. You can Install the additional dependencies
    sudo apt install bison flex m4

Configure the bash-shell 

  • Once only you need to Run the following command to set the OpenFOAM working environment
echo "source /opt/OpenFOAM/OpenFOAM-v2012/etc/bashrc" >> ~/.bashrc
source $HOME/.bashrc

 Checking of Open FOAM Installation

  • OpenFOAM installation needs to verify by running any one OpenFOAM tutorial
  • You have to copy any tutorial ( e.g. cavity) to the Ubuntu folder
    • Enter command in the terminal to make a mesh of geometry (blockMesh)
    • Run it by typing: icoFoam
mkdir -p /mnt/c/Users/<USER>/tutorial
cd /mnt/c/Users/<USER>/tutorial
cp -ar $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity .
cd cavityNew

Installation  of Pre and POst Processing Tools

Para View and FoamToTecplot

  • Install Para View to visualize mesh files, a GUI-based post-processing tool
  • The case can be visually checked using Para View.
  • You can download the Para view and install it within Windows 10: Download Para view
  • Click here : Userguide of Paraview
