Detailed Description

Class for integrating the bilinear form a(u,v) := (Q u, v), where u=(u1,...,un) and v=(v1,...,vn); ui and vi are defined by scalar FE through standard transformation.

VectorMassIntegrator::VectorMassIntegrator

(

)

[inline]

Construct an integrator with coefficient 1.0.

References IntRule, MQ, Q, Q_order, and VQ.

VectorMassIntegrator::VectorMassIntegrator	(	Coefficient &	q,
		int	qo = 0
	)		[inline]

Construct an integrator with scalar coefficient q. If possible, save memory by using a scalar integrator since the resulting matrix is block diagonal with the same diagonal block repeated. ;-)

VectorMassIntegrator::VectorMassIntegrator	(	VectorCoefficient &	q,
