Redesigned design optimization API and voltage components plot

​
Redesigned design optimization API

Design optimization has been restructured with a cleaner API for configuring models, parameters, experiments, and objectives. A new strict schema enforces valid configurations and enables automatic frontend form generation, making it easier to set up and validate optimization runs.Find out more →

Voltage components plot

A new voltage components plot lets you visualize the individual contributions to cell voltage — such as open-circuit voltage, ohmic losses, and reaction overpotentials — for deeper insight into cell behavior during simulations.
Fixes
  • Fixed cells from other projects appearing in cell selection lists.
  • Empty simulation data now correctly shows a failed status instead of a blank result.
Fixes
  • Fixed reaction overpotential (eta_r) calculation bug.
