int	index () const
	Returns this discontinuity index in the father set.

	Returns the cell group index associated with this discontinuity, if any. This is the index of the group in the list returned by GmCellMesh::cellGroupIds() Returns -1 for an unspecified cell group.

virtual int	propertyIndex (int propertySet) const
	Given a property set number, returns the line of the property set that contains property values for this discontinuity. The returned value can be used to get a property from a property accessor retrieved from the discontinuity set.

virtual int	numElements () const =0
	A generic interface to return the original discontinuity data number of geometric elements. For 2d meshes it will be either the number of polyline segments or the number of edges. For 3d meshes, the number of triangles or the number of faces.

virtual int	numPoints () const =0
	A generic interface to return the original discontinuity data number of points.

virtual int	numIntersections () const =0
	A generic interface to return the number of intersections between the mesh and the user given geometry. Is the number of line segments or faces (triangles an/or quads) in the intersection set.

Static Protected Member Functions
template<class T , class V >
static T *	loadIntoVector (LuaTable &tab, V validator, int n, int realSize, QString discontinuityId, const char msg, const GmLogCategory &logger)
	Allocate a vector of type T with at most tab.size() * n elements and reads the tab contents into it. Expects that tab is a vector with sub-tables storing n elements. Each loaded element is passed as a variant to the validator function, that should return the converted value to T. The validator should also fill a status variable that says if the value is ok (>=0), ignored (-1) or invalid(-2). Invalid values raise an error and causes loadIntoVector() to log a message and return NULL. Ignored values are simply not added to the result vector (which will be resized accordingly) and are targeted into ignoring cells that don't belong to the current mesh partition. Returns the real size of the vector in the realSize output parameter.

Detailed Description

The geometric representation for a single discontinuity from the Discontinuity set. For 2D meshes, it is a polyline. For 3D meshes is a triangulated surface. It can also be represented by edge or face lists.

Member Function Documentation

◆ clearGeometry()

virtual void GmDiscontinuity::clearGeometry ( )

pure virtual

Clears the original discontinuity geometry information, releasing memory.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ extendGeometry()

virtual bool GmDiscontinuity::extendGeometry	(	GmCellMesh *	sMesh,
		double	size,
		const GmLogCategory &	logger )

pure virtual

\breif A generic interface for extending the original geometry by size units. The 'sMesh' is a empty mesh that supports addition of elements and topological consults.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ findIntersections()

virtual bool GmDiscontinuity::findIntersections ( const GmLogCategory & logger )

inlinevirtual

Builds the element intersection list for this discontinuity.

Reimplemented in GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ numElements()

virtual int GmDiscontinuity::numElements ( ) const

pure virtual

A generic interface to return the original discontinuity data number of geometric elements. For 2d meshes it will be either the number of polyline segments or the number of edges. For 3d meshes, the number of triangles or the number of faces.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ numIntersections()

virtual int GmDiscontinuity::numIntersections ( ) const

pure virtual

A generic interface to return the number of intersections between the mesh and the user given geometry. Is the number of line segments or faces (triangles an/or quads) in the intersection set.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ numPoints()

virtual int GmDiscontinuity::numPoints ( ) const

pure virtual

A generic interface to return the original discontinuity data number of points.

virtual void GmDiscontinuity::printGeometry	(	const GmLogCategory &	logger,
		GmLogLevel	level ) const

pure virtual

Prints the discontinuity geometry information.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ printIntersections()

virtual void GmDiscontinuity::printIntersections	(	const GmLogCategory &	logger,
		GmLogLevel	level ) const

inlinevirtual

Prints the discontinuity-mesh intersection information.

Reimplemented in GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ propertyIndex()

virtual int GmDiscontinuity::propertyIndex ( int propertySet ) const

inlinevirtual

Given a property set number, returns the line of the property set that contains property values for this discontinuity. The returned value can be used to get a property from a property accessor retrieved from the discontinuity set.

The propertySet number is local to the discontinuity set and varies between 0 and GmDiscontinuitySet::numPropertySets() - 1.

◆ setGeometry()

virtual void GmDiscontinuity::setGeometry	(	double *	dvec,
		int	nd,
		int *	ivec,
		int	ni )

◆ usedGeometryMemory()

virtual size_t GmDiscontinuity::usedGeometryMemory ( ) const

pure virtual

Returns an estimative of the memory used by the discontinuity geometry in bytes.

It returns in general the variable memory that depends on the number of lines in a polyline, edges or faces for boundary lists or points & triangles for surfaces, ignoring "constant" sizes.

Implemented in GmEdgeListDiscontinuity, GmFaceListDiscontinuity, GmPolylineDiscontinuity, and GmTriSurfaceDiscontinuity.

◆ usedIntersectionMemory()

virtual size_t GmDiscontinuity::usedIntersectionMemory ( ) const

inlinevirtual

Returns an estimative of the memory used by the intersection data in bytes.
