Building the Doxygen help for OpenFOAM

The HTML documentation of OpenFOAM can be built using the Doxygen software. Images in the documentation are generated using "dot", a program within the graphviz software package. To build the documentation on the Ubuntu GNU/Linux system, for example, the user should install both doxygen and graphviz packages, e.g. by typing in a terminal window:

• sudo apt-get install doxygen graphviz

The Doxygen documentation will build automatically for a user that is configured to run OpenFOAM, i.e. has environment variables such as $WM_PROJECT_DIR set. The user must also ensure they have write permission for the directory that Doxygen writes files to.

The Doygen configuration file, Doxyfile, in the $WM_PROJECT_DIR/doc/Doxygen directory is configured to work with Doxygen versions 1.6.3-1.8.5.

The Header, Footer, and Stylesheet are generated automatically:

• doxygen -w html header.html footer.html customdoxygen.css

See: https://www.stack.nl/~dimitri/doxygen/manual/customize.html

In the $WM_PROJECT_DIR/doc/Doxygen directory type

• ./Allwmake

which will generate the $WM_PROJECT_DIR/doc/Doxygen/html directory containing the OpenFOAM source code documentation. Load the index.html file into a browser, e.g.

• firefox $WM_PROJECT_DIR/doc/Doxygen/html/index.html
