Programming

Complete Programming Courses

• Hoste and Jasak video series on programming.
• Tips by Gerhard Holzinger Source Code and Programming (Chapter IX).
• Nilsson's introduction to programming in OpenFOAM.

C++

• Basics of C++ by Hakan Nilsson.

Intro: Compilation and Testing

• The screencast tutorials by Stefan Radl provide details on compilation and basic testing of new code.
• Lee's compact introduction to compilation using existing code.

Implementation of Initial and Boundary Conditions

• This tutorial by Gavin Tabor covers the implementation of custom boundary conditions.
• Guerrero describes how to implement and test BCs using codeStream.
• Guerrero describes field initialization using codeStream.
• Guerrero describes how to implement a basic solver from scratch.
• Guerrero describes how to add a passive scalar (or the convection-diffusion equation) to a basic solver.

Complete model implementation

• Alletto describes how to couple two different physical problems in OpenFoam. In this specific case you will use the equation of motion of a membrane with pretension to impose the movement of the mesh at a given boundary.

Customizing solvers

• Gavin Tabor describes in this tutorial how to customize solver and implement a new constitutive model.
• Isabelle Choquet and Håkan Nilsson teaches how to implement new thermophysical model and additional transport equation.
• Vakhrushev's slides illustrate how to modify a solver.
• Code Development describes now you can implement your own souce code in OpenFOAM.
