Models management

Studio now has dedicated pages for managing models — browse a list of available models, view model details, and create new models. Parameterized model details are also viewable from the model pages.Find out more →

Data fit performance improvements

The data fit UI is now significantly more responsive. React memoization and element collapsing prevent unnecessary re-renders, and RPC payload sizes have been reduced for batch job updates.
Fixes
  • Fixed batch payload format for nested dictionaries.
  • Fixed pipeline data fit element fetching.
Improvements
  • Penalties and constraints refactored to use PyBaMM expressions for greater flexibility.
  • SciPy DifferentialEvolution optimizer now supports parallelization.
Fixes
  • Fixed MSMR validation plot range clipping and a type-conversion bug with large integers.
  • Fixed bugs with lumped model and ECM compatibility.
  • Fixed parameter reverse-parsing.
