virtual void mfem::TMOP_Combo_QualityMetric::AddQualityMetric	(	TMOP_QualityMetric *	tq,
		double	wt = `1.0`
	)

void mfem::TMOP_Combo_QualityMetric::AssembleH	(	const DenseMatrix &	Jpt,
		const DenseMatrix &	DS,
		const double	weight,
		DenseMatrix &	A
	)		const

virtual

Evaluate the derivative of the 1st Piola-Kirchhoff stress tensor and assemble its contribution to the local gradient matrix 'A'.

Parameters

[in]	Jpt	Represents the target->physical transformation Jacobian matrix.
[in]	DS	Gradient of the basis matrix (dof x dim).
[in]	weight	Quadrature weight coefficient for the point.
[in,out]	A	Local gradient matrix where the contribution from this point will be added.

Computes weight * d(dW_dxi)_d(xj) at the current point, for all i and j, where x1 ... xn are the FE dofs. This function is usually defined using the matrix invariants and their derivatives.

Implements mfem::TMOP_QualityMetric.

Definition at line 46 of file tmop.cpp.

void mfem::TMOP_Combo_QualityMetric::EvalP	(	const DenseMatrix &	Jpt,
		DenseMatrix &	P
	)		const

virtual

Evaluate the 1st Piola-Kirchhoff stress tensor, P = P(Jpt).

Parameters

[in]	Jpt	Represents the target->physical transformation Jacobian matrix.
[out]	P	The evaluated 1st Piola-Kirchhoff stress tensor.

Implements mfem::TMOP_QualityMetric.

Definition at line 33 of file tmop.cpp.

double mfem::TMOP_Combo_QualityMetric::EvalW ( const DenseMatrix & Jpt ) const

virtual

Evaluate the strain energy density function, W = W(Jpt).

Parameters

[in] Jpt Represents the target->physical transformation Jacobian matrix.

Implements mfem::TMOP_QualityMetric.

Definition at line 23 of file tmop.cpp.

virtual void mfem::TMOP_Combo_QualityMetric::SetTargetJacobian ( const DenseMatrix & Jtr_ )

inlinevirtual

Specify the reference-element -> target-element Jacobian matrix for the point of interest.

The specified Jacobian matrix, Jtr, can be used by metrics that cannot be written just as a function of the target->physical Jacobian matrix, Jpt.

Reimplemented from mfem::TMOP_QualityMetric.
