Other Documentation

OpenFOAM is open source. The source code of OpenFOAM is a vital source of documentation in itself. As well as the actual code itself, most applications, for example, contain descriptions of what they do, there are descriptions of various models with supporting references, etc..

The use of most applications can be learnt by looking at the corresponding example case in the $FOAM_TUTORIALS directory in the OpenFOAM release. The Allrun scripts show how many applications are executed.
