Detailed Description

Abstract class representing a field of an internal variable. Field represent the spatial distribution of certain variable and is able to evaluate its value at any point of interest. The field is usually associated to the specific domain.

It uses MaterialMappingAlgorithm interface to perform interpolation. Note, that some classes implementing MaterialMappingAlgorithm may require that elements implement corresponding interface.

Constructor & Destructor Documentation

InternalVariableField()

oofem::InternalVariableField::InternalVariableField	(	InternalStateType	ist,
		FieldType	b,
		MaterialMappingAlgorithmType	mma_type,
		Domain *	d )

Constructor. Creates a internal variable field of given type associated to given domain.

Parameters

ist	Physical meaning of field.

Member Function Documentation

evaluateAt() [1/2]

int oofem::InternalVariableField::evaluateAt ( FloatArray & answer, const FloatArray & coords, ValueModeType mode, TimeStep * tStep )

overridevirtual

Evaluates the field at given point.

Parameters

coords	Coordinates of the point of interest
answer	Field evaluated at coordinate.
tStep	Time step to evaluate for.
mode	Mode of value (total, velocity,...).

Returns

Zero if ok, otherwise nonzero.

Use MaterialMappingAlgorithm classes to do the job

evaluateAt() [2/2]

int oofem::InternalVariableField::evaluateAt ( FloatArray & answer, DofManager * dman, ValueModeType mode, TimeStep * tStep )

overridevirtual

Evaluates the field at given DofManager. This potentially can be resolved quickly, as receiver data may be described using values at dofManagers. Here an additional issue exists: one needs to make sure, that passed dman is from the same domain, so that its number can be used to perform suggested quick evaluation.

If this is not the case (the field is described differently), the response can be evaluated using dofman coordinates in a standard way.

Parameters

[out]	answer	Evaluated field for dman.
	dman	Reference to dofManager.
	mode	Mode of value (total, velocity,...).
	tStep	Time step to evaluate for.

Returns

Zero if ok, nonzero Error code (0-ok, 1-failed)

Implements oofem::Field.

giveClassName()

const char * oofem::InternalVariableField::giveClassName ( ) const

inlineoverridevirtual

Returns

Class name of the receiver.

Implements oofem::Field.

restoreContext()

void oofem::InternalVariableField::restoreContext ( DataStream & stream )

overridevirtual

Restores the receiver state previously written in stream.

Parameters

Exceptions

Throws

an ContextIOERR exception if error encountered.

Implements oofem::Field.

Definition at line 73 of file intvarfield.C.

saveContext()

void oofem::InternalVariableField::saveContext ( DataStream & stream )

overridevirtual

Stores receiver state to output stream.

Parameters

Output stream.

Exceptions

Throws

an ContextIOERR exception if error encountered.
