Required arguments

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

Optional arguments

type: A SymbolicConstant specifying the type of material coefficients for the piezoelectric property. Possible values are STRAIN and STRESS. The default value is STRESS.
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=STRESS, the table data specify the following:

$e_{1 11}^{φ}$ .
$e_{1 22}^{φ}$ .
$e_{1 33}^{φ}$ .
$e_{1 12}^{φ}$ .
$e_{1 13}^{φ}$ .
$e_{1 23}^{φ}$ .
$e_{2 11}^{φ}$ .
$e_{2 22}^{φ}$ .
$e_{2 33}^{φ}$ .
$e_{2 12}^{φ}$ .
$e_{2 13}^{φ}$ .
$e_{2 23}^{φ}$ .
$e_{3 11}^{φ}$ .
$e_{3 22}^{φ}$ .
$e_{3 33}^{φ}$ .
$e_{3 12}^{φ}$ .
$e_{3 13}^{φ}$ .
$e_{3 23}^{φ}$ .
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=STRAIN, the table data specify the following:

$d_{1 11}^{φ}$ .
$d_{1 22}^{φ}$ .
$d_{1 33}^{φ}$ .
$d_{1 12}^{φ}$ .
$d_{1 13}^{φ}$ .
$d_{1 23}^{φ}$ .
$d_{2 11}^{φ}$ .
$d_{2 22}^{φ}$ .
$d_{2 33}^{φ}$ .
$d_{2 12}^{φ}$ .
$d_{2 13}^{φ}$ .
$d_{2 23}^{φ}$ .
$d_{3 11}^{φ}$ .
$d_{3 22}^{φ}$ .
$d_{3 33}^{φ}$ .
$d_{3 13}^{φ}$ .
$d_{3 23}^{φ}$ .
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

Optional arguments

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

Return value

None.

Exceptions

None.

Members

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