Detailed Description

Class representing field defined by nodal values associated to given domain. Field represent the spatial distribution of certain variable. The implementation allows to set individual dofMan values; However, in the current implementation does not allow to specify values for different time steps. It is also possible to create a separate, virtual domain by adding particular nodes and elements with nodal values.

addElement()

void oofem::DofManValueField::addElement	(	int	i,
		const char *	name,
		const IntArray &	nodes )

Add element to the domain

addNode()

void oofem::DofManValueField::addNode	(	int	i,
		const FloatArray &	coords )

Add node to the domain

evaluateAt() [1/2]

int oofem::DofManValueField::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.

Implements oofem::Field.

evaluateAt() [2/2]

int oofem::DofManValueField::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 dof managers. 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 dof manager.
	mode	Mode of value (total, velocity,...).
	tStep	TimInternalStateType valID, IntArray regions, TimeStep *tStepe step to evaluate for.

Returns

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