Detailed Description

Evolves an electrical potential equation.

$\grad \left( \sigma \grad V \right)$

where $ V $ is electrical potential and $\sigma$ is the electrical current.

To provide a Joule heating contribution according to:

Differential form of Joule heating - power per unit volume:

$\frac{d(P)}{d(V)} = J \cdot E$

where $ J $ is the current density and $ E $ the electric field. If no magnetic field is present:

$J = \sigma E$

The electric field given by

$E = \grad V$

Therefore:

$\frac{d(P)}{d(V)} = J \cdot E = (sigma E) \cdot E = (sigma \grad V) \cdot \grad V$

Usage

Minimal example by using constant/faOptions:

jouleHeatingSource1
{
    // Mandatory entries (unmodifiable)
    type                 jouleHeatingSource;

    // Mandatory entries (runtime modifiable)
    anisotropicElectricalConductivity true;

    // Optional entries (runtime modifiable)
    T                   <Tname>;
    nIter               -1;

    // Conditional mandatory entries (runtime modifiable)

        // when the entry "sigma" is present
        sigma           <Function1>;

        // when when the entry "sigma" is not present
        // read "sigma" from file

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: jouleHeatingSource	word	yes	-
`anisotropicElectricalConductivity`	Flag to indicate that if the electrical conductivity is anisotropic	bool	yes	-
`T`	Name of operand temperature field	word	no	T
`sigma`	Electrical conductivity as a function of temperature	table	no	-
`nIter`	Number of iterations for electrical potential equation solution	label	no	-1

The inherited entries are elaborated in:

Note

anisotropicElectricalConductivity=true enables anisotropic (tensorial) electrical conductivity.
anisotropicElectricalConductivity=false enables isotropic (scalar) electrical conductivity.
The electrical conductivity can be specified using either:

If the sigma entry is present the electrical conductivity is specified as a function of temperature using a Function1 type.
If not present the sigma field will be read from file.
If the anisotropicElectricalConductivity flag is set to true, sigma should be specified as a tensor quantity.
