Viscous(...)

This method creates a Viscous object.

Path

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

Required arguments

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

Optional arguments

law: A SymbolicConstant specifying the creep law. Possible values are STRAIN, TIME, and USER. The default value is STRAIN.
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 law=STRAIN or law=TIME, the table data specify the following:

$A$ .
$n$ .
$m$ .
$f$ .
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 law=USER, the table data specify the following:

$f$ .
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 Viscous object.

Exceptions

None.

setValues(...)

This method modifies the Viscous object.

Required arguments

None.

Optional arguments

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

Return value

None.

Exceptions

None.

Members

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

In addition, the Viscous object can have the following member:

potential: A Potential object.
