Mathematics, Numerics, Derivations and OpenFOAM®

The publication was started in 2015 and is also available on ResearchGate. Tobias tries to keep the book up-to-date.

The publication named »Mathematics, Numerics, Derivations and OpenFOAM®« is the outcome of Tobias' time during his Ph.D. at the Montanuniverität Leoben (Austria). In the beginning, the book was more like a summary of different equations. After the community got a 30-page outline, a lot of feedback about an extension was given. Thus, Tobias decided to go on writing the summary, which ended in the actual book. 


— The book is going to be translated to Indian language voluntarily from native people —

The book contains the general equations used for computational fluid dynamics. However, compared to other literature, Tobias made the derivation of the equations fundamental and showed every single step. A volume element is used to demonstrate the origin of the mass conservation, momentum equation, and the different kinds of energy equations. Additionally, the transformation of the equations from the Cartesian / Einstein-summation form to the vector and integral form is described as well as the conversion from conservative (Euler) to non-conserved (Lagrangian) is prescribed. 


— Several hundreds hours are already spend for writing the book —

Tobias tries do extend the book from time to time and keep the material and code snippets that are presented in the book up to date to the OpenFOAM Foundation version. The free version is a present to the OpenFOAM® community. Tobias hopes that people understand that the full version does cost a bit as people otherwise do not support his work. 

The book is related to People who

  • are interested in the fundamental equations
  • are interested in the basic Reynolds-Averaging approach
  • are interested in the closure problem
  • want to see the derivations of equations
  • are interested in the PIMPLE algorithm 
  • are interested in the divDevREff and divDevRhoREff function
  • are interested in a few OpenFOAM® classes
  • are interested in a brief equation to c++ transfer
  • are interested in general computational fluid dynamics knowledge
  • ... just check the public version

The book is not related to 

  • fundamental OpenFOAM® programming
  • a detailed description of the usage of OpenFOAM® 
  • to turbulence modeling, e.g., different turbulence models
  • Numerical schemes and their implementation
  • A guide of best practice to use OpenFOAM®
  • advanced visualization using DAKOTA®

— Tobias provides the LaTeX files on the new GitHub account —

The new vision of Tobias is to make his material freely available for everybody and forever. Thus, he decided to publish the LaTeX files for the book related to the free version. The paid one is still in a private repository. However, this allows the community to do the following:

  • Translate the book on a new »language« branch
  • Extend different topics and make a pull request
  • Remove mistakes directly while making a pull request
  • Having direct access to the files and repository also allows the transparency in changes (commits)
