Python Battery Mathematical Modelling (PyBaMM)

Features

• Renamed MSMR parameters from symbols to written out names with units as a non-breaking change with a deprecation warning. (#5027)

Optimizations

• Update docs, examples and tests to use IDAKLUSolver. (#4996)
• Add a solver option to change on_extrapolation behavior to "error", "warn", or "ignore" on extrapolation events. (#4993)
• Improve reliability of CasadiAlgebraicSolver and added an option for the step_tol of the Newton iteration. (#4985)
• Speed up calculation of variable sensitivities in ProcessedVariable (#5000)

Bug fixes

• Fixed a bug in the QuickPlot which would return empty values for 1D variables at the beginning and end of a timespan. (#4991)
• Fixed a bug in the Exponential1DSubMesh where the mesh was not being created correctly for non-zero minimum values. (#4989)
• Fixed sensitivity calculation for pybamm.DiscreteTimeSum. (#5007)

Breaking changes

• Remove sensitivity functionality for Casadi and Scipy solvers, only pybamm.IDAKLU solver can calculate sensitivities. (#4975)
