Detailed Description

A piecewise vector-valued coefficient with the pieces keyed off the element attribute numbers.

A value of zero will be returned for any missing attribute numbers.

This object will not assume ownership of any VectorCoefficient objects passed to it. Consequently, the caller must ensure that the individual VectorCoefficient objects are not deleted while this PWVectorCoefficient is still in use.

Note: The keys may either be domain attribute numbers or boundary attribute numbers. If the PWVectorCoefficient is used with a domain integrator the keys are assumed to be domain attribute numbers. Similarly, if the PWVectorCoefficient is used with a boundary integrator the keys are assumed to be boundary attribute numbers.

Constructor & Destructor Documentation

mfem::PWVectorCoefficient::PWVectorCoefficient ( int vd )

inlineexplicit

Constructs a piecewise vector coefficient of dimension vd.

Definition at line 543 of file coefficient.hpp.

mfem::PWVectorCoefficient::PWVectorCoefficient	(	int	vd,
		const Array< int > &	attr,
		const Array< VectorCoefficient * > &	coefs
	)

inline

Construct the coefficient using arrays describing the pieces.

Parameters

vd	- dimension of the vector-valued result
attr	- an array of attribute numbers for each piece
coefs	- the corresponding array of VectorCoefficient pointers Any missing attributes or NULL coefficient pointers will result in a zero vector being returned for that attribute.

Note: Ownership of the VectorCoefficient objects will NOT be transferred to this object.
