Detailed Description

template<class DOP>
class ngfem::DiffOp< DOP >

Differential Operator.

Base-class for template-polymorphismus. Provides application and transpose-application. Operations can be applied for one integration point, or for the whole integration rule at once.

Member Function Documentation

template<class DOP>

template<typename FEL , typename MIP , class TVX , class TVY >

static void ngfem::DiffOp< DOP >::Apply	(	const FEL &	fel,
		const MIP &	mip,
		const TVX &	x,
		TVY &	y,
		LocalHeap &	lh
	)		[inline, static]

Applies the B-matrix.

Computes matrix-vector product with the B-matrix

template<class DOP>

template<typename FEL , typename MIP , typename MAT >

static void ngfem::DiffOp< DOP >::GenerateMatrix	(	const FEL &	fel,
		const MIP &	mip,
		MAT &	mat,
		LocalHeap &	lh
	)		[inline, static]

Computes the B-matrix.

The height is DIM_DMAT, the width is fel.GetNDof(). FEL is the FiniteElement type specified in the BDB-Integrator mip is the mapped integration point containing the Jacobi-Matrix MAT is the resulting matrix (usually a FixedHeightMatrix)

Reimplemented in ngfem::DiffOpCurl3d, ngfem::DiffOpCurl, ngfem::DiffOpDiv< D >, ngfem::DiffOpIdBoundarySys< D, SYSDIM >, ngfem::DiffOpIdSys< D, SYSDIM >, and ngfem::DiffOpGradientRotSym< D >.
