New and Improved Functionality in Version 4.3a

  • Film Resistance is now available in the Electrolyte-Electrode Boundary Interface and Electrolyte-Electrode Domain Interface features in all Electrochemistry physics (except Primary Current Distribution and Electrode, Shell).
  • The Electrodeposition, Secondary and Electrodeposition, Tertiary Nernst-Planck physics interfaces now implement deformation of the geometry frame instead of the mesh frame. The name of the Electrodeposition, Moving Mesh branch in the Model Wizard has been changed accordingly to Electrodeposition, Deformed Geometry.

New Model

A new model, Fountain Flow Effects on a Rotating Wire, explores the convective flow effects in a cell with a rotating wafer. This model requires the CFD Module.

Backward Compatibility vs. 4.3

Brinkman Equations and Free and Porous Media Flow

The momentum equations in the Brinkman Equations interface and the Free and Porous Media Flow interface have been corrected. The term -Qbr·u/εp2 in the right hand side previously lacked the factor 1/εp2 , where εp is the porosity.

Reacting Flow Interface Name Change

The Reacting Flow interfaces have been renamed Reacting Flow in Porous Media. Opening a model using either the Reacting Flow, Diluted Species or the Reacting Flow, Concentrated Species interface, the interface is renamed Reacting Flow in Porous Media.

Weak Constraints Update for Fluid Flow Interfaces

The weak constraint formulation for some boundary conditions in the following interfaces have been updated:

  • Laminar Flow
  • Brinkman Equations
  • Free and Porous Media Flow

See CFD Module for details.

Mobility

In physics user interfaces modeling migration (Transport of Diluted Species, Transport of Concentrated Species, Reacting Flow in Porous Media, Diluted Species, Reacting Flow in Porous Media, Concentrated Species, Tertiary Current Distribution, and Nernst-Planck) anisotropic mobility is now supported, and the mobility can be set to following the Nernst-Einstein relation. The default setting when making new models has been changed to use the Nernst-Einstein relation. Model Java-files generated prior to 4.3a using Migration will have to be modified manually to account for these changes.
