pure virtual

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

Referenced by oofem::GeometryBasedEI::evaluateEnrFuncDerivAt().

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

inlinevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

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

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

virtual

Setups the input record string of receiver.

Parameters

input Dynamic input record to be filled by receiver.

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

Referenced by oofem::GeometryBasedEI::evaluateEnrFuncJumps().

int oofem::EnrichmentFunction::giveNumberOfDofs ( ) const

inline

Definition at line 86 of file enrichmentfunction.h.

Referenced by oofem::EnrichmentItem::giveNumberOfEnrDofs().

virtual IRResultType oofem::EnrichmentFunction::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.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.

Returns: IRResultType

Reimplemented from oofem::FEMComponent.
