The Electroanalysis Model Wizard Entry
The Electroanalysis (tcd) () Model Wizard entry, found under the Electrochemistry branch () adds a Tertiary Current Distribution, Nernst–Planck interface to the model with the Electrolyte Charge Conservation Model set to Electroanalysis by default.
The Electroanalysis option is suitable for modeling mass transport of diluted species in electrolytes using the diffusion-convection equation, solving for electroactive species concentrations.
The Tertiary Current Distribution, Nernst–Planck Interface also features options for modeling cyclic voltammetry and electrochemical impedance spectroscopy.
Use this Model Wizard entry to model electroanalytical problems with electrolyte solutions containing a large quantity of inert “supporting” electrolyte. Ohmic loss is assumed to be negligible.
The Model Wizard entry is available in 1D, 2D, and 3D as well as for axisymmetric components in 1D and 2D.
The default dependent variables are the molar concentrations, c1 and c2, of the two electroactive species in a redox couple and the electric potential, phis, which is solved for either in the Electrode or Porous Electrode domain feature.
