Detailed Description

Material class using an external .in file as a description of the substructure of a transport problem (in this case seepage).

The external .in file must be of the stokesflowvelocityhomogenization type.

The response is computed by applying a pressure gradient over the domain and after solving, computing the mean velocity (which is the seepage velocity).

Member Function Documentation

MaterialStatus * oofem::RVEStokesFlow::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.

Reimplemented from oofem::TransportMaterial.

void oofem::RVEStokesFlow::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).

Implements oofem::TransportMaterial.

virtual double oofem::RVEStokesFlow::giveCharacteristicValue	(	MatResponseMode	mode,
		GaussPoint *	gp,
		TimeStep *	tStep
	)

inlinevirtual

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).

Implements oofem::TransportMaterial.

Definition at line 120 of file rvestokesflow.h.

virtual const char* oofem::RVEStokesFlow::giveClassName ( ) const

inlinevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

Definition at line 126 of file rvestokesflow.h.

void oofem::RVEStokesFlow::giveFluxVector	(	FloatArray &	answer,
		GaussPoint *	gp,
		const FloatArray &	grad,
		const FloatArray &	field,
		TimeStep *	tStep
	)

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.

virtual

Returns the integration point corresponding value in Reduced form.

Parameters

answer	Contain corresponding ip value, zero sized if not available.
gp	Integration point to which the value refers.
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::RVEStokesFlow::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.

Parameters

ir	Input record to initialize from.

Returns: IRResultType
