Detailed Description

Implementation of symmetry nonlocal barrier. It allows to specify up to three planes (orthogonal ones) of symmetry It then modifies the integration weights of source points to take into account symmetry of the averaged field.

Member Function Documentation

applyConstraint()

void oofem::SymmetryBarrier::applyConstraint ( const double cl, const FloatArray & c1, const FloatArray & c2, double & weight, bool & shieldFlag, const NonlocalMaterialExtensionInterface & nei )

overridevirtual

Abstract method modifying the integration weight between master (c1) and source (c2) point.

Parameters

	cl	Characteristic length of nonlocal model.
	c1	Coordinates of master point.
	c2	Coordinates of source point.
	weight	Original integration weight; on output modified weight.
[out]	shieldFlag	Set to true if shielding is activated.
	nei	The element with the non local material extension.

Implements oofem::NonlocalBarrier.

calculateMinimumDistanceFromBoundary()

double oofem::SymmetryBarrier::calculateMinimumDistanceFromBoundary ( const FloatArray & coords )

inlineoverridevirtual

Abstract method calculating the minimum distance of the Gauss Point from the nonlocal boundaries

Parameters

coords	Coordinates of the Gauss Point
maxPossibleDistance	Distance from the boundary beyond which the nonlocal radius(as it is interpreted in each weight function) becomes equal to the user-defined

Returns

the minimum value of the minimum distance from nonlocal boundary and maxPossibleDistance

Implements oofem::NonlocalBarrier.

Definition at line 78 of file symmetrybarrier.h.

giveClassName()

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

inlineoverridevirtual

Returns

Class name of the receiver.

Implements oofem::FEMComponent.

Definition at line 82 of file symmetrybarrier.h.

giveInputRecordName()

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

inlineoverridevirtual

Returns

Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 81 of file symmetrybarrier.h.

References _IFT_SymmetryBarrier_Name.

initializeFrom()

void oofem::SymmetryBarrier::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
