Detailed Description

Abstract base class for all nonlocal barriers. The purpose of this class is to model barrier for nonlocal averaging process (visibility criterion, symmetry condition). Usually, the given remote integration point influences to the source point nonlocal average if the averaging function at source point and evaluated for remote point has nonzero value. The barrier allows to exclude additional points, which may be close enough, but due to several reasons there is no influence between these points (for example, they can be separated by a notch).

Member Function Documentation

applyConstraint()

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

pure virtual

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.

Implemented in oofem::PolylineNonlocalBarrier, and oofem::SymmetryBarrier.

calculateMinimumDistanceFromBoundary()

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

pure virtual

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

Implemented in oofem::PolylineNonlocalBarrier, and oofem::SymmetryBarrier.
