Detailed Description

template<typename SCALAR>
class projects::dpg::ProductElementVectorProvider< SCALAR >

Class providing element vectors associated with linear forms on cartesian/product spaces.

Template Parameters

SCALAR

type for the entries of the element matrices. Ususally 'double'

Note

This interface class complies with the requirements for the template parameter ELEM_VEC_COMP of the function AssembleVectorLocally().

This class provides element vectors associated to linar forms \( l: V \rightarrow \mathbb R \) on a product space (c.f. ProductUniformFEDofHandler, ProductUniformFESpace)

\[ V = V_0 \times V_1 \times \dots \times V_{m-1} \]

that has the following structure

\[ l((v_1, \dots v_{m-1})) = \sum_{k} l_k(v_{j_k}) \]

with

\[ l_k : V_{j_k} \rightarrow \mathbb{R} \]

The evaluation of element vectors for such "building block" linear forms \( l_k \) is performed by means of the SubElementVectorProvider interface.

This class takes a vector of such SubElementVectorProviders in its constructor and builds the element vector for the bilinear form \( l \) by stacking together the sub vectors (using the rules of local dof ordering specified in ProductUniformFEDofHandler).

Eval()

template<typename SCALAR >

ProductElementVectorProvider< SCALAR >::ElemVec projects::dpg::ProductElementVectorProvider< SCALAR >::Eval

(

const lf::mesh::Entity &

cell

)

main routine for the computation of element vectors

Parameters

cell	refernce to the cell for which the element vector should be computed

Returns

a small vector, containing the element vector.

All cells are considered active in the default implementation.

This method is meant to be overloaded if assembly should be restricted to a subset of cells.
