Now you can go read the User Guide, where you may have more than one choice:
- Which you can find a local copy of the User Guide by running the following command:
ls -A1 $WM_PROJECT_DIR/doc/Guides*/*UserGuide*.pdf
- You should see two available formats: A4 and US-Letter.
- But if it instead tells you that there is No such file or directory, then either the OpenFOAM environment is possibly not properly activated, or the version no longer provides PDF documentation with the installation.
You can find the more recent OpenFOAM Documentation online that is provided by ESI-OpenCFD at the following page: OpenFOAM® Documentation - but be careful that if your version is older than the current release, then the instructions on the documentation may not work, because the documentation is updated with each new release.
That said, if you need to upgrade custom code that was built with the older versions, they do provide instructions on what changed in the source code, that you will need to adapt to.
