Python Battery Mathematical Modelling (PyBaMM)

Features

• Added additional user-configurable options to the (IDAKLUSolver) and adjusted the default values to improve performance. (#4282)
• Added the diffusion element to be used in the Thevenin model. (#4254)

Optimizations

• Update IDAKLU tests and benchmarks to use adaptive time stepping. (#4390)
• Improved adaptive time-stepping performance of the (IDAKLUSolver). (#4351)
• Improved performance and reliability of DAE consistent initialization. (#4301)
• Replaced rounded Faraday constant with its exact value in bpx.py for better comparison between different tools. (#4290)

Bug Fixes

• Fixed memory issue that caused failure when output variables were specified with (IDAKLUSolver). (#4379)
• Fixed bug where IDAKLU solver failed when output variables were specified and an event triggered. (#4300)

Breaking changes

• Replaced have_jax with has_jax, have_idaklu with has_idaklu, and have_iree with has_iree (#4398)
• Remove deprecated function pybamm_install_jax (#4362)
• Removed legacy python-IDAKLU solver. (#4326)
