◆ Action()

template<int SDim, int Dim, typename complex_t >
template<typename T_result_t , typename Q_t , typename q_t , typename S_data_t >
static MFEM_ALWAYS_INLINE void mfem::TMassKernel< SDim, Dim, 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
kthe element number
FJt [M x Dim x SDim x NE] - Jacobian transposed, data member in F
QCoefficientEval<>::Type
qCoefficientEval<>::Type::result_t
Rval_qpts [M x NC x NE] - in/out data member in R val_qpts *= w det(J)

◆ Assemble()

template<int SDim, int Dim, typename complex_t >
template<typename T_result_t , typename Q_t , typename q_t , int qpts>
static MFEM_ALWAYS_INLINE void mfem::TMassKernel< SDim, Dim, complex_t >::Assemble ( const int  k,
const T_result_t &  F,
const Q_t &  Q,
const q_t &  q,
TVector< qpts, complex_t > &  A 
)
inlinestatic

Method defining partial assembly. Result in A is the quadrature-point dependent part of element matrix assembly (as opposed to part that is same for all elements), A = w det(J)

Parameters
kthe element number
FJt [M x Dim x SDim x NE] - Jacobian transposed, data member in F
QCoefficientEval<>::Type
qCoefficientEval<>::Type::result_t
A[M] - partially assembled scalars

Definition at line 117 of file tbilininteg.hpp.

◆ MultAssembled()

template<int SDim, int Dim, typename complex_t >
template<int qpts, typename S_data_t >
static MFEM_ALWAYS_INLINE void mfem::TMassKernel< SDim, Dim, complex_t >::MultAssembled ( const int  k,
const TVector< qpts, complex_t > &  A,
S_data_t &  R 
)
inlinestatic

Method for partially assembled action.

Parameters
kthe element number
A[M] - partially assembled scalars
Rval_qpts [M x NC x NE] - in/out data member in R val_qpts *= A
