Electrodeposition Module
New Functionality in Version 5.2a
Nernst-Planck-Poisson Equations Multiphysics Interface
A new Nernst-Planck-Poisson Equations predefined multiphysics interface is now available in the Model Wizard. The Nernst-Planck-Poisson Equations interface adds the Electrostatics and Transport of Diluted Species interfaces to the model, together with new multiphysics coupling nodes: Potential Coupling and Space Charge Density Coupling.
External Short Boundary Condition
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.
Electrochemical Heat Source
A new Electrochemical Heat Source 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.
Thermodynamic Equilibrium in Electrode Reactions
The Electrode Reactions node now support a new Thermodynamic Equilibrium (Primary Condition in the Secondary Current Distribution interface) electrode kinetics type that assumes zero overpotential (negligible voltage losses).
Porous Electrode and Edge Electrode Improvements
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).
Far-field approximation in Current Distribution, BEM
The Current Distribution, BEM interface now supports a new far-field approximation assembly method. In combination with an iterative solver, the far-field approximation can significantly reduce the computational time and memory usage for large problems.
Improved Solver Defaults
An automatic predictor is now used in auxiliary sweeps for Stationary study steps in the Electrochemistry interfaces. The automatic predictor lowers computational time in, for instance, polarization sweeps.
