  • OpenFOAM is a great project!
  • OpenFOAM supports a collaborative environment. Everybody is invited.
  • OpenFOAM gives a perpetual value to its users.
  • OpenFOAM stands for Open Source Field Operation and Manipulation.
  • OpenFOAM is the world leading open-source tool for Computational Fluid Dynamics.
  • OpenFOAM is designed as an easily extensible package of tools for numerical simulations (mainly CFD).
  • OpenFOAM is based on the Finite Volume Method, see https://en.wikipedia.org/wiki/Finite_volume_method.
  • The code is distributed under GNU General Public License
  • OpenFOAM has a large user base across most areas of engineering and science, from both commercial and academic organizations.
  • OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electro-magnetics.
  • OpenFOAM is a free, open source CFD software package developed by:
    • CFD Direct is the primary developer of OpenFOAM, on behalf of the OpenFOAM Foundation, the copyright holder and licensor of OpenFOAM
    • OpenCFD Ltd, owner of the OpenFOAM Trademark, owned by ESI Group

Aim of this manual

The aim of this manual is to explain those steps and components, which are not directly obvious from tutorials and source code. All the tutorial cases are already pre-set and can be run immediately.

The expected level of OpenFOAM knowledge is at least user knowledge (User OpenFOAM training participation or approximately equal level https://www.cfdsupport.com/openfoam-training.html).

Although this manual shows the complete path how to set the cases from the beginning, it is written with effort to serve as a part of the individual training on this methodology.

ParaView is an open source multiple-platform application for interactive, scientific visualization. It has a client–server architecture to facilitate remote visualization of datasets, and generates level of detail (LOD) models to maintain interactive frame rates for large datasets. It is an application built on top of the Visualization Tool Kit (VTK) libraries. Where VTK is a set of libraries that provide visualization services for data, task, and pipeline parallelism, ParaView is an application designed for data parallelism on shared-memory or distributed-memory multicomputers and clusters. It can also be run as a single-computer application.

ParaView offers the possibility to extend its functionality in several directions. This encompasses modifications to the GUI and implementation of new plugins.
