Detailed Description

template<typename IterationIdTag, typename FieldsTag, typename FixedSourcesTag, typename OperandTag, typename OperatorAppliedToOperandTag, typename CoordsTag, typename ArraySectionIdTag = void>
struct LinearSolver::Actions::BuildMatrix< IterationIdTag, FieldsTag, FixedSourcesTag, OperandTag, OperatorAppliedToOperandTag, CoordsTag, ArraySectionIdTag >

Build the explicit matrix representation of the linear operator and optionally invert it directly to solve the problem.

This is useful for debugging and analysis only, not to actually solve the elliptic problem (that should happen iteratively).

Add the actions to the action list to build the matrix. The ApplyOperatorActions template parameter are the actions that apply the linear operator to the OperandTag. Also add the amr_projectors to the list of AMR projectors and the register_actions

Template Parameters
IterationIdTagUsed to keep track of the iteration over all matrix columns. Should be the same that's used to identify iterations in the ApplyOperatorActions.
FieldsTagThe solution will be stored here (if direct solve is enabled).
FixedSourcesTagThe source b in the problem Ax = b. Only used if direct solve is enabled.
OperandTagWill be set to unit vectors, with the '1' moving through all points over the course of the iteration.
OperatorAppliedToOperandTagWhere the ApplyOperatorActions store the result of applying the linear operator to the OperandTag.
CoordsTagThe tag of the coordinates observed alongside the matrix for volume data visualization.
ArraySectionIdTagCan identify a subset of elements that this algorithm should run over, e.g. in a multigrid setting.
