Conductivity(...)

This method creates a Conductivity object.

Path

mdb.models[name].materials[name].Conductivity
session.odbs[name].materials[name].Conductivity

Required arguments

table: A sequence of sequences of Floats specifying the items described below.

Optional arguments

type: A SymbolicConstant specifying the type of conductivity. Possible values are ISOTROPIC, ORTHOTROPIC, and ANISOTROPIC. The default value is ISOTROPIC.
temperatureDependency: A Boolean specifying whether the data depend on temperature. The default value is OFF.
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:

Conductivity, $k$ .
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:

$k_{11}$ .
$k_{22}$ .
$k_{33}$ .
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:

$k_{11}$ .
$k_{12}$ .
$k_{22}$ .
$k_{13}$ .
$k_{23}$ .
$k_{33}$ .
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 Conductivity object.

Exceptions

RangeError.

setValues(...)

This method modifies the Conductivity object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the Conductivity method.

Return value

None.

Exceptions

RangeError.

Members

The Conductivity object has members with the same names and descriptions as the arguments to the Conductivity method.
