PROCESS is the reactor systems code at CCFE. More information on PROCESS can be found on the PROCESS webpage.
PROCESS was originally a Fortran code, but is now Python-wrapped Fortran. In order to use PROCESS, the Fortran must be compiled and a Python-Fortran interface generated for the Python to import. Once built, it can be installed and run as a Python package.
Please see the installation guide and the usage guide. Once installed, the examples directory provides Jupyter notebooks for interactively demonstrating usage of PROCESS, which is a good place to start. The examples/README.md provides more help.
To read about how the code works and the modules in it see the documentation, which is hosted on Gitlab Pages.
Process uses a mixture of tracking and testing to ensure code reliability. Tests are run on each branch and ensure the output of keys functions are correct. Tracking, on the other hand, shows graphs of a variables changes over time, and what commit caused the change.
Our tracker can be found here: http://process.gitpages.ccfe.ac.uk/process/tracking.html Documentation on testing can be found here: http://process.gitpages.ccfe.ac.uk/process/development/testing/
Please see the CONTRIBUTING.md for guidance on how to contribute to PROCESS. Further information is found in the development section of the documentation.
A list of publications using PROCESS is given here, including two papers outlining the physics and engineering models in PROCESS.
