Constructor & Destructor Documentation

oofem::FluidCrossSection::FluidCrossSection ( int  n,
Domain d 
)

Constructor.

Creates cross section with number n belonging to domain d.

Parameters
nCross section number.
dDomain for cross section.

Member Function Documentation

int oofem::FluidCrossSection::checkConsistency ( )
virtual

Allows programmer to test some internal data, before computation begins.

For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns
Nonzero if receiver is consistent.

Reimplemented from oofem::FEMComponent.

Definition at line 70 of file fluidcrosssection.C.

References oofem::FEMComponent::checkConsistency(), oofem::FEMComponent::domain, oofem::Domain::giveMaterial(), and matNumber.

int oofem::FluidCrossSection::estimatePackSize ( DataStream buff,
GaussPoint ip 
)
virtual

Estimates the necessary pack size to hold all packed data of receiver.

The corresponding material model service is invoked. The nature of packed data is typically material model dependent.

Parameters
buffCommunication buffer.
ipIntegration point.
Returns
Estimate of pack size.

Implements oofem::CrossSection.

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

Returns
Class name of the receiver.

double oofem::FluidCrossSection::giveDensity ( GaussPoint gp)
virtual
FluidDynamicMaterial * oofem::FluidCrossSection::giveFluidMaterial ( )
void oofem::FluidCrossSection::giveInputRecord ( DynamicInputRecord input)
virtual

Setups the input record string of receiver.

Parameters
inputDynamic input record to be filled by receiver.

virtual const char* oofem::FluidCrossSection::giveInputRecordName ( ) const
inlinevirtual
Returns
Input record name of the receiver.

Implements oofem::FEMComponent.

int oofem::FluidCrossSection::giveIPValue ( FloatArray answer,
GaussPoint ip,
InternalStateType  type,
TimeStep tStep 
)
virtual

Returns the integration point corresponding value in Reduced form.

Parameters
answercontain corresponding ip value, zero sized if not available
ipIntegration point.
typeDetermines the type of internal variable.
tStepTime step.
Returns
Nonzero if o.k, zero otherwise.

Material * oofem::FluidCrossSection::giveMaterial ( IntegrationPoint ip)
virtual

Returns the material associated with the GP.

Default implementation uses gp->giveMaterial() for backwards compatibility, but it should be overloaded in each specialized cross-section.

Implements oofem::CrossSection.

IRResultType oofem::FluidCrossSection::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_OPTIONAL_FIELD
Parameters
irInput record to initialize from.
Returns
IRResultType

bool oofem::FluidCrossSection::isCharacteristicMtrxSymmetric ( MatResponseMode  rMode)
virtual

Check for symmetry of stiffness matrix.

Default implementation returns true. It can be moved to base Cross section class in the future.

Parameters
rModeResponse mode of material.
Returns
True if stiffness matrix of receiver is symmetric.

Reimplemented from oofem::CrossSection.

Definition at line 92 of file fluidcrosssection.C.

int oofem::FluidCrossSection::packUnknowns ( DataStream buff,
TimeStep tStep,
GaussPoint ip 
)
virtual

Pack all necessary data of integration point (according to element parallel_mode) into given communication buffer.

The corresponding material model service for particular integration point is invoked. The nature of packed data is material model dependent. Typically, for material of "local" response (response depends only on integration point local state) no data are exchanged. For "nonlocal" constitutive models the send/receive of local values which undergo averaging is performed between local and corresponding remote elements.

Parameters
buffCommunication buffer.
tStepSolution step.
ipIntegration point.
Returns
Nonzero if successful.

Implements oofem::CrossSection.

Definition at line 116 of file fluidcrosssection.C.

int oofem::FluidCrossSection::unpackAndUpdateUnknowns ( DataStream buff,
TimeStep tStep,
GaussPoint ip 
)
virtual

Unpack and updates all necessary data of given integration point (according to element parallel_mode) into given communication buffer.

See also
packUnknowns service.
Parameters
buffCommunication buffer.
tStepSolution step.
ipIntegration point.
Returns
Nonzero if successful.
