Shell Electrodynamic Potential Model Reference

In the same way as for the Electrodynamic Potential model, this model calculates the electric potential according to Eqn. (4277). From the electric potential, Simcenter STAR-CCM+ calculates the electric field Eqn. (4232) and the electric current density Eqn. (4228).

Shell Electrodynamic Potential Model Properties

Secondary Gradients

Neglect or include the boundary secondary gradients for diffusion and/or the interior secondary gradients at mesh faces.

On: Default value. Solves for interior and boundary types of secondary gradient.
Off: Does not solve for either type of secondary gradient.
Interior Only: Solves for the interior secondary gradients only.
Boundaries Only: Solves for the boundary secondary gradients only.

Material Properties

In the same way as you can define the electrical conductivity within the material properties of a region using the Electrodynamic Potential model, you can use the Shell Electrodynamic Potential model to define the electrical conductivity within the material properties of a fluid film phase or solid shell region. However, the Electrochemical Species method is incompatible with the Shell Electrodynamic Potential model.

See Electrodynamic Potential Model Reference: Material Properties.

Initial Conditions

In the same way as you can define the electrical conductivity initial condition for a region when using the Electrodynamic Potential model, you can define the electrical conductivity initial condition for a fluid film phase or solid shell region when using the Shell Electrodynamic Potential model.

See Electrodynamic Potential Model Reference: Initial Conditions.

Interface Settings

In the same way as you can define interface conditions and values for interfaces between regions that use the Electrodynamic Potential model, you can define conditions and values for the following interface types for fluid films that use the Shell Electrodynamic Potential model.

Internal Interfaces
Fluid-Film Interfaces: between the fluid film and the neighboring gas region.
Contact Interfaces: between the fluid film and a neighboring solid region.
Mapped Contact Interfaces: not supported by the Shell Electrodynamic Potential model. However, if the simulation uses another model that supports the Mapped Contact Interface (for example, Segregated Solid Energy) on both interfacing regions, then the Mapped Contact Interface can be used provided that the Electrodynamic Potential model is not selected in the region that interfaces with the shell region. For information on properties, see Mapped Contact Interface.

See Electrodynamic Potential Model Reference: Interface Settings.

Field Functions

The same field functions are available as are described for the Electrodynamic Potential model.
