Parameters
----------
intrinsicComponents
A sequence of Ints specifying the components of relative motion for which the
contributing term is defined. Possible values are 1 ≤≤ *intrinsicComponents* ≤≤ 6. Only
available components can be specified if the DerivedComponent object is being referenced
by a Potential object. This is not the case if the DerivedComponent object is referenced
by a ConnectorFriction object directly. The default value is an empty sequence.
table
A sequence of sequences of Floats specifying components numbers and temperature and
field values. Each sequence of the table data specifies:The first intrinsic component
number.If applicable, the second intrinsic component number.Etc.If applicable, the first
independent component number.If applicable, the second independent component
number.Etc.If applicable, the temperature value.If applicable, the value of the first
field variable.If applicable, the value of the second field variable.Etc.The default
value is an empty sequence.
termOperator
A SymbolicConstant specifying the method for combining contributing terms: square root
of a sum of the squares, direct sum, or Macauley sum. Possible values are RSS, SUM, and
MACAULEY. The default value is RSS.
termSign
A SymbolicConstant specifying the overall sign for the contributing term. Possible
values are POSITIVE and NEGATIVE. The default value is POSITIVE.
localDependency
A Boolean specifying whether the table data depend on either components of relative
position or components of constitutive relative motion. The default value is OFF.
indepCompType
A SymbolicConstant specifying whether localDependency refers to components of relative
position or components of constitutive relative motion. Possible values are POSITION and
MOTION. The default value is POSITION.The *indepCompType* argument applies only if
*localDependency*=ON.
indepComponents
A sequence of Ints specifying the independent components included in the derived
component definition. Possible values are 1 ≤≤ *indepComponents* ≤≤ 6. Only available
components can be specified. The *indepComponents* argument applies only if
*localDependency*=ON. The default value is an empty sequence.
tempDependency
A Boolean specifying whether the table data depend on temperature. The default value is
OFF.
fieldDependencies
An Int specifying the number of field variable dependencies. The default value is 0.
Returns
-------
A CDCTerm object.
Raises
------
ValueError and TextError.
