Detailed Description

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

FieldsTag	The solution will be stored here (if direct solve is enabled).
FixedSourcesTag	The source `b` in the problem `Ax = b`. Only used if direct solve is enabled.
OperandTag	Will be set to unit vectors, with the '1' moving through all points over the course of the iteration.
OperatorAppliedToOperandTag	Where the `ApplyOperatorActions` store the result of applying the linear operator to the `OperandTag`.
CoordsTag	The tag of the coordinates observed alongside the matrix for volume data visualization.
ArraySectionIdTag	Can identify a subset of elements that this algorithm should run over, e.g. in a multigrid setting.
