The Corrosion, Primary (), the Corrosion, Secondary (), and the Corrosion, Tertiary Nernst-Planck (), found under the Electrochemistry > Corrosion, Deformed Geometry branch () in the Add Physics menu, are predefined multiphysics interfaces for time-dependent modeling of deformations that occur as a result of deposition/dissolution processes in electrochemical cells.

By choosing one of the above multiphysics interfaces, the corresponding Current Distribution interface and a Deformed Geometry interface are added to the component. Deforming Electrode Surface and Nondeforming Boundary multiphysics coupling nodes that couple electrode reactions to boundary velocities are also added by default. The predefined couplings are set up so that the deforming geometry velocity is set to the total depositing velocity on boundaries where deposition/dissolution processes occur, and zero on all other boundaries.
