odb_Diffusivity&
Diffusivity(const odb_SequenceSequenceDouble& table,
            const odb_String& type,
            const odb_String& law,
            bool temperatureDependency,
            int dependencies);

Required arguments

table: An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

type: An odb_String specifying the type of diffusivity. Possible values are "ISOTROPIC", "ORTHOTROPIC", and "ANISOTROPIC". The default value is "ISOTROPIC".
law: An odb_String specifying the diffusion behavior. Possible values are "GENERAL" and "FICK". The default value is "GENERAL".
temperatureDependency: A Boolean specifying whether the data depend on temperature. The default value is false.
dependencies: An Int specifying the number of field variable dependencies. The default value is 0.

Table data

If type=ISOTROPIC, the table data specify the following:

Diffusivity, $D$ .
Concentration, $c$ .
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

If type=ORTHOTROPIC, the table data specify the following:

$D_{11}$ .
$D_{22}$ .
$D_{33}$ .
Concentration, $c$ .
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

If type=ANISOTROPIC, the table data specify the following:

$D_{11}$ .
$D_{12}$ .
$D_{22}$ .
$D_{13}$ .
$D_{23}$ .
$D_{33}$ .
Concentration, $c$ .
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

Return value

A Diffusivity object.
