Parameters
kthe element number
FJt [M x Dim x SDim x NE] - Jacobian transposed, data member in F
Q- CoefficientEval<>::Type
q- CoefficientEval<>::Type::result_t
Rgrad_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

)
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.

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 x Dim*(Dim+1)/2] - partially assembled Dim x Dim symm. matrices A [M x Dim x Dim] - partially assembled Dim x Dim matrices A = (w/det(J)) adj(J) adj(J)^t

)
inlinestatic

Method for partially assembled action.

Parameters
