Classes
struct	CoefficientEval
struct	f_asm_data
	Partially assembled data type for one element with the given number of quadrature points. This type is used in full element matrix assembly. Stores one general (non-symmetric) 2 x 2 matrix per point. More...
struct	p_asm_data
	Partially assembled data type for one element with the given number of quadrature points. This type is used in partial assembly, and partially assembled action. Stores one symmetric 2 x 2 matrix per point. More...

static MFEM_ALWAYS_INLINE void mfem::TDiffusionKernel< 2, 2, complex_t >::Action ( const int  k, const T_result_t &  F, const Q_t &  Q, const q_t &  q, S_data_t &  R  )

inlinestatic

Method used for un-assembled (matrix free) action.

Parameters

k	the element number
F	Jt [M x Dim x SDim x NE] - Jacobian transposed, data member in F
Q	CoefficientEval<>::Type
q	CoefficientEval<>::Type::result_t
R	grad_qpts [M x SDim x NC x NE] - in/out data member in R grad_qpts = (w/det(J)) adj(J) adj(J)^t grad_qpts

static MFEM_ALWAYS_INLINE void mfem::TDiffusionKernel< 2, 2, complex_t >::Assemble ( const int  k, const T_result_t &  F, const Q_t &  Q, const q_t &  q, asm_type &  A  )

inlinestatic

Method defining partial assembly. The pointwise Dim x Dim matrices are stored as symmetric (when asm_type == p_asm_data, i.e. A.layout.rank == 2) or non-symmetric (when asm_type == f_asm_data, i.e. A.layout.rank == 3) matrices. A = (w/det(J)) adj(J) adj(J)^t.

Parameters

k	the element number
F	Jt [M x Dim x SDim x NE] - Jacobian transposed, data member in F
Q	CoefficientEval<>::Type
q	CoefficientEval<>::Type::result_t
A	[M x Dim*(Dim+1)/2] partially assembled Dim x Dim symm. matrices
A	[M x Dim x Dim] partially assembled Dim x Dim matrices

inlinestatic

Method for partially assembled action.

Parameters

k	the element number
A	[M x Dim*(Dim+1)/2] - partially assembled Dim x Dim symmetric matrices
R	grad_qpts [M x SDim x NC x NE] - in/out data member in R grad_qpts = A grad_qpts
