 description = OpenCCM is a compartmental modelling software package which is based on recently-developed fully automated flow alignment compartmentalization methods. It is primarily intended for large-scale flow-based processes where there is weak coupling between composition changes, e.g. through (bio)chemical reactions, and convective mass transport in the system.
