Th new Sacrificial Edge Anode node is a customized node for modeling slender sacrificial anodes along geometric edges. It is available in the Secondary Current Distribution interface. The
Sacrificial Edge Anode node makes it possible to model changing cathodic protection properties of the anodes as they dissolve in time-dependent simulations.
A new External Short boundary condition has been introduced that allows for short circuiting of electrode surfaces, porous electrodes, and electrodes through an external lumped resistance. The feature is available as a separate boundary node, applicable to Electrode and
Porous Electrode domain nodes, and as a Boundary Condition option in the
Electrode surface node. The feature is available in the following physics interfaces: Primary Current Distribution; Secondary Current Distribution; Tertiary Current Distribution, Nernst Planck;, Lithium-Ion Battery; Battery with Binary Electrode; and Lead-Acid Battery.
A new Electrochemical Heat Source node is now available as a Multiphysics coupling node. The
Electrochemical Heat Source multiphysics node offers an alternate way of coupling the electrochemical heat sources from any Electrochemistry interface into a Heat Transfer interface.
The Electrode Reactions node now supports a new Thermodynamic Equilibrium (Primary Condition in the Secondary Current Distribution interface) electrode kinetics type that assumes zero overpotential (negligible voltage losses).
The Porous Electrode and
Edge Electrode nodes now support the addition of film resistances and dissolving-depositing species (previously this was only supported in the
Electrode Surface feature).
