MaterialStatus * oofem::IsotropicHeatTransferMaterial::CreateStatus ( GaussPoint * gp ) const

virtual

Creates new copy of associated status and inserts it into given integration point.

Parameters

gp	Integration point where newly created status will be stored.

Returns: Reference to new status.

void oofem::IsotropicHeatTransferMaterial::giveCharacteristicMatrix	(	FloatMatrix &	answer,
		MatResponseMode	mode,
		GaussPoint *	gp,
		TimeStep *	tStep
	)

virtual

Computes characteristic matrix of receiver in given integration point.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters

answer	Contains result.
mode	Material response mode.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).

	)

virtual

Computes the characteristic value of receiver in given integration point, respecting its history.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters

mode	Material response mode.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).

	)

virtual

Returns the flux for the field and its gradient.

Todo:: { Should the field variable just be a scalar? This might change when we rethink the coupled-fields approach. Now its either just [temperature], or [temperature, concentration] so to cover both cases there is a floatarray. }

Parameters

answer	The flux.
gp	Gauss point.
grad	Gradient of the primary field, usually the main input.
field	The value of the field itself.
tStep	Active time step.

Todo:: Shouldn't the conductivity typically depend on the primary field and/or its gradient?

Parameters

type	Determines the type of internal variable.
tStep	Determines the time step.

Returns: Nonzero if the assignment can be done, zero if this type of variable is not supported.

IRResultType oofem::IsotropicHeatTransferMaterial::initializeFrom ( InputRecord * ir )

virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.
