Standard libraries

3.7 Standard libraries

The libraries with the OpenFOAM distribution are in the $FOAM_LIB/$WM_OPTIONS directory, reached quickly by typing lib at the command line. Again, the names are prefixed by lib and reasonably descriptive, e.g. incompressibleTransportModels contains the library of incompressible transport models. For ease of presentation, the libraries are separated into two types:

General libraries: those that provide general classes and associated functions listed in Table 3.7;
Model libraries: those that specify models used in computational continuum mechanics, listed in Table 3.8, Table 3.9 and Table 3.10.
