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.

Member Function Documentation

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

virtual

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

	)

virtual

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.
