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.

		const FloatArray &	c2,
		double &	weight,
		bool &	shieldFlag,
		NonlocalMaterialExtensionInterface *	nei
	)

virtual

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

Parameters

	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.

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

inlinevirtual

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.

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

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

inlinevirtual

Returns: Input record name of the receiver.

IRResultType oofem::SymmetryBarrier::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.
