Member Function Documentation

evaluateEnrFuncAt()

virtual void oofem::EnrichmentFunction::evaluateEnrFuncAt ( double & oEnrFunc, const FloatArray & iPos, const double & iLevelSet ) const

pure virtual

Implemented in oofem::DiscontinuousFunction, oofem::HeavisideFunction, and oofem::RampFunction.

evaluateEnrFuncDerivAt()

virtual void oofem::EnrichmentFunction::evaluateEnrFuncDerivAt ( FloatArray & oEnrFuncDeriv, const FloatArray & iPos, const double & iLevelSet, const FloatArray & iGradLevelSet ) const

pure virtual

Implemented in oofem::DiscontinuousFunction, oofem::HeavisideFunction, and oofem::RampFunction.

giveClassName()

const char * oofem::EnrichmentFunction::giveClassName ( ) const

inlineoverridevirtual

Returns

Class name of the receiver.

Implements oofem::FEMComponent.

Reimplemented in oofem::HeavisideFunction, and oofem::RampFunction.

Definition at line 88 of file enrichmentfunction.h.

giveInputRecord()

void oofem::EnrichmentFunction::giveInputRecord ( DynamicInputRecord & input )

overridevirtual

Setups the input record string of receiver.

Parameters

input

Dynamic input record to be filled by receiver.

Reimplemented from oofem::FEMComponent.

Definition at line 51 of file enrichmentfunction.C.

Referenced by initializeFrom().

giveJump()

virtual void oofem::EnrichmentFunction::giveJump ( std ::vector< double > & oJumps ) const

pure virtual

Returns the discontinuous jump in the enrichment function when the lvel set function changes sign, e.g. 1.0 for Heaviside, 2.0 for Sign and 0.0 for abs enrichment. Used for combination of cohesive zones and XFEM.

Implemented in oofem::DiscontinuousFunction, oofem::HeavisideFunction, and oofem::RampFunction.

giveNumberOfDofs()

int oofem::EnrichmentFunction::giveNumberOfDofs ( ) const

inline

Definition at line 89 of file enrichmentfunction.h.

References numberOfDofs.

initializeFrom()

void oofem::EnrichmentFunction::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.

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

Reimplemented from oofem::FEMComponent.
