Detailed Description

Class for integrating the bilinear form a(u,v) := (Q grad u, v) in either 2D or 3D and where Q is an optional coefficient (of type scalar, matrix, or diagonal matrix) u is in H1 and v is in H(Curl) or H(Div). Partial assembly (PA) is supported but could be further optimized by using more efficient threading and shared memory.

◆ AddMultPA()

void mfem::MixedVectorGradientIntegrator::AddMultPA	(	const Vector &	x,
		Vector &	y
	)		const

protectedvirtual

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

Method for partially assembled transposed action.

Perform the transpose action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.
