1) Commercial CFD Solvers without Automatic Meshing

 How to Install ANSYS CFD Solvers 

  • There are CFD solvers  which are  widely used in both academia and industries
  • Students can use up to maximum 500,000 cells for CFD simulations using ANSYS FLUENT
  • They provide a free version for students
  • Refer to the user guide for CFD modeling
  • Check your system hardware before installing CFD analysis software
  • Students can Tecplot for post-processing of CFD results. Tecplot has good control over streamlines and vectors.

  Application and Modules:

  • Geometry Tools: ANSYS Space claim, ANSYS Work Bench
  • Meshing platform: ANSYS Mesher, ICEM CFD, FLUENT Mesher
  • CFD Solver: FLUENT, CFX
  • Post-processing: CFD-Post, ANSYS EnSight

 New Update in ANSYS FLUENT 2022 R1

  1. MPI is integrated with GPU enabled for parallel computing: Example the speed of 4 GPU is same more than 100 CPUs
  2. Boundary conditions can be given by selecting surfaces in the model rather than GUI from selection panels
  3. Add or remove options for cells in ANSYS FLUENT Meshing
  4. Dedicated Aerospace Module for external aerodynamic simulations
  5. Runtime Discrete Fourier Transform (DFT) for the entire domain
  6. Sponge layer for acoustic damping
  7. Sound composition
  8. Two new Efficient Mesh Adaption methods in FLUENT: 1) Hessian error based, 2) Anisotropic adaption
  9. Advanced Electronic Cooling Module in FLUENT for printed circuit boards (PCBs)

2) 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 generate 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 

  3) Open source  CFD Solvers  (Free Software)

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

  Application and Modules:

 User Guide of Open Foam

3.1 How to Install Open FOAM in Windows

3.1 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

3.2 Download and installation of Open FOAM Files

  1. Download OpenFOAM-v2012:   OpenFOAM-v2012-windows10.tgz
  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

3.2 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

3.3 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
blockMesh
icoFoam

2.4  Installation of Para View

  • Install Para View to visualize mesh files, GUI-based post-processing tool
  • The case can be visually checked using ParaView
