BasisFunctionsProvidedExternalQuad: set of basis functions and derivatives at the quadrature points provided directly at construction. The quadrature points are referenced externally, they are not kept as a copy inside the object.

Constructor & Destructor Documentation

BasisFunctionsProvidedExternalQuad::BasisFunctionsProvidedExternalQuad	(	const std::vector< double > &	ShapesInput,
		const std::vector< double > &	DShapesInput,
		const std::vector< double > &	QuadratureWeights,
		const std::vector< double > &	QuadratureCoords
	)			`[inline]`

Constructor.

In the following,
NQuad = QuadratureWeights.size(), the total number of quadrature points
NShapes = ShapesInput.size()/QuadratureWeights.size(), total number of shape functions provided
spd = QuadratureCoords().size/QuadratureWeights.size(), number of spatial dimensions

Parameters:

	ShapesInput,:	Values of each shape function at each quadrature point. ShapesInput[ q*NShapes + a] = value of shape function "a" at quadrature point "q"
	DShapesInput,:	Values of each shape function derivative at each quadrature point. DShapesInput[ qNShapesspd + a*spd + i] = value of shape function "a" derivative in the i-th direction at quadrature point "q"
	QuadratureWeights,:	QuadratureWeights[q] contains the value of the quadrature weight at quad point "q"
	QuadratureCoords,:	QuadratureCoords[q*spd+i] contains the i-th coordinate of the position of quadrature point "q"

If not derivatives of shape functions are available, just provide and empty vector as DShapesInput

BasisFunctionsProvidedExternalQuad::BasisFunctionsProvidedExternalQuad	(	size_t	NShapes,
		const std::vector< double > &	DShapesInput,
		const std::vector< double > &	QuadratureWeights,
		const std::vector< double > &	QuadratureCoords
	)			`[inline]`

Constructor.

In the following no shape functions are provided. An empty vector will be
place in its place.
NQuad = QuadratureWeights.size(), the total number of quadrature points
spd = QuadratureCoords().size/QuadratureWeights.size(), number of spatial dimensions NDerivatives = LocalDShapes.size()/(NumberOfShapes*LocalWeights.size())

Parameters:

	NShapes	Number of shape functions for which derivatives are offered
	DShapesInput,:	Values of each shape function derivative at each quadrature point. DShapesInput[ qNShapesspd + a*spd + i] = value of shape function "a" derivative in the i-th direction at quadrature point "q"
	QuadratureWeights,:	QuadratureWeights[q] contains the value of the quadrature weight at quad point "q"
	QuadratureCoords,:	QuadratureCoords[q*spd+i] contains the i-th coordinate of the position of quadrature point "q"
