void oofem::InterfaceElem1d::computeBmatrixAt	(	GaussPoint *	gp,
		FloatMatrix &	answer,
		int	lowerIndx = 1,
		int	upperIndx = ALL_STRAINS )

overrideprotectedvirtual

Computes the geometrical matrix of receiver in given integration point. The product of this matrix (assembled at given integration point) and element displacement vector is element strain vector. If lowerIndx and upperIndx parameters are specified, answer is formed only for strains within this interval. This will affects the size of answer.

Parameters

gp	Integration point for which answer is computed.
answer	Geometric matrix of receiver.
lowerIndx	If specified, answer is formed only for strain with index equal and greater than lowerIndx. This parameter has default value 1 (answer is formed from first strain).
upperIndx	If specified, answer is formed only for strain with index less and equal than upperIndx. This parameter has default value ALL_STRAINS (answer is formed for all strains).

◆ computeLumpedMassMatrix()

void oofem::InterfaceElem1d::computeLumpedMassMatrix	(	FloatMatrix &	answer,

Implements oofem::Element.

Definition at line 94 of file interfaceelement1d.h.

◆ giveInputRecordName()

const char * oofem::InterfaceElem1d::giveInputRecordName ( ) const

inlineoverridevirtual

Returns: Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 89 of file interfaceelement1d.h.

References _IFT_InterfaceElem1d_Name.

◆ giveIntegrationDomain()

integrationDomain oofem::InterfaceElem1d::giveIntegrationDomain ( ) const

inlineoverridevirtual

Returns integration domain for receiver, used to initialize integration point over receiver volume. Default behavior is taken from the default interpolation.

Returns: Integration domain of element.

Reimplemented from oofem::Element.

Definition at line 95 of file interfaceelement1d.h.

References oofem::_Point.

◆ giveMaterialMode()

MaterialMode oofem::InterfaceElem1d::giveMaterialMode ( )

overridevirtual

Returns material mode for receiver integration points. Should be specialized.

Returns: Material mode of element.

Reimplemented from oofem::Element.

◆ initializeFinish()

void oofem::InterfaceElem1d::initializeFinish ( )

overridevirtual

Finishes the initialization. Note that initializeFrom may be called multiple times. The initializeFinish typycally performs the input parameter checking (if compulsory parameters set, etc.) After initializeFinish, DOFs and other components may be created.

◆ testElementExtension()

int oofem::InterfaceElem1d::testElementExtension ( ElementExtension ext )

inlineoverridevirtual

Tests if the element implements required extension. ElementExtension type defines the list of all available element extensions.

Parameters

ext	Extension to be tested.

Returns: Nonzero if extension supported.
