Detailed Description

Class for a nonlinear fictitious transport material. The constitutive equation is given as

\[\mathbf{w}=-\left( 1+C \mid \mid \mathbf{\nabla} p \mid\mid^{\alpha}\right) \mathbf{\nabla} p \]

where \( \boldsymbol{w} \) is the seepage velocity, \( \alpha \) and \( C \) are constants and \( p \) is the pressure.

◆ giveCharacteristicValue()

double oofem::NonlinearMassTransferMaterial::giveCharacteristicValue	(	MatResponseMode	mode,
		GaussPoint *	gp,
		TimeStep *	tStep ) const

overridevirtual

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.

Returns: Class name of the receiver.

◆ giveInputRecordName()

const char * oofem::NonlinearMassTransferMaterial::giveInputRecordName ( ) const

inlineoverridevirtual

Returns: Input record name of the receiver.

◆ giveIPValue()

int oofem::NonlinearMassTransferMaterial::giveIPValue	(	FloatArray &	answer,
		GaussPoint *	gp,
		InternalStateType	type,
		TimeStep *	tStep )

overridevirtual

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.

◆ initializeFrom()

void oofem::NonlinearMassTransferMaterial::initializeFrom ( InputRecord & ir )

overridevirtual

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. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization
