Detailed Description

Class for an anisotropic linear transport material.

The constitutive equation is given as

\[ \mathbf{w}=-\mathbf{K} \mathbf{\nabla} p \]

where $ \mathbf{w} $ is the seepage velocity, $ \mathbf{K} $ is the permeability which is given in the input file and $ p $ is the pressure.

Member Function Documentation

void oofem::AnisotropicMassTransferMaterial::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
answerContains result.
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

Implements oofem::TransportMaterial.

double oofem::AnisotropicMassTransferMaterial::giveCharacteristicValue ( MatResponseMode  mode,
GaussPoint gp,
TimeStep tStep 
)
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
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).

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

Returns
Class name of the receiver.

void oofem::AnisotropicMassTransferMaterial::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
answerThe flux.
gpGauss point.
gradGradient of the primary field, usually the main input.
fieldThe value of the field itself.
tStepActive time step.

IRResultType oofem::AnisotropicMassTransferMaterial::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.

IR_GIVE_FIELD
IR_GIVE_OPTIONAL_FIELD
Parameters
irInput record to initialize from.
Returns
IRResultType
Todo:
Why hardcode this for 2d ? Just take the whole matrix as the input instead and not worry about it.
