During October 2024, Alex Bills developed the CoupledVariable framework for the pybamm-team/PyBaMM repository, enabling inter-model coupling within battery modeling workflows. He introduced the CoupledVariable class and integrated it into the discretisation process and expression tree, allowing models to reference variables defined in other models. Alex expanded the BaseModel to include a coupled_variables dictionary, supporting inter-model dependencies and improving model flexibility. His work included comprehensive unit testing, enhancements to initialization routines for domain support, and improved copy behavior. Throughout the project, Alex maintained code quality by implementing pre-commit checks and CI-triggering commits, utilizing Python and object-oriented programming principles.

October 2024 monthly summary for pybamm-team/PyBaMM: Delivered the CoupledVariable framework enabling inter-model coupling. Key changes include introduction of CoupledVariable class, integration into discretisation, and a new BaseModel.coupled_variables dictionary to represent inter-model dependencies. Expanded tests and initialization to cover domain support and improved copy behavior. Implemented CI-triggering commits and maintained pre-commit checks to ensure code quality. Commits contributing to the feature include: b9b721fa2b6a35fe8c155e24b6f8a1318e44483c (add coupled variable to expression tree and discretisation); f30749187ae2c777e8c21ff5b45031610e735c31 (add test; add coupledvariable dict to model); 4d638c9ebb984065c71c653c2f10d41bddcf53ad (pre-commit); 0d4f12d4e45ff1feef68e413f59d413abf1c2e7d (Trigger CI); c259bb0e6046dc5fd591e39d487ba6cf340b2915 (add tests for coverage; valentin comments).
