class SweepChunk

Sweep work function.

Subclassed by opensn::AAHSweepChunk, opensn::AAHSweepChunkRZ, opensn::CBCSweepChunk

Public Types

using MomentCallbackFunc = std::function<void(SweepChunk *sweeper, AngleSet *angle_set)>: Convenient typdef for the moment call back function. See moment_callbacks.

Public Functions

inline SweepChunk(std::vector<double> &destination_phi, std::vector<double> &destination_psi, const std::shared_ptr<MeshContinuum> &grid, const SpatialDiscretization &discretization, const std::vector<UnitCellMatrices> &unit_cell_matrices, std::vector<CellLBSView> &cell_transport_views, const std::vector<double> &densities, const std::vector<double> &source_moments, const LBSGroupset &groupset, const std::map<int, std::shared_ptr<MultiGroupXS>> &xs, int num_moments, int max_num_cell_dofs)

inline virtual void Sweep(AngleSet &angle_set): Sweep chunks should override this.

inline virtual void SetAngleSet(AngleSet &angle_set): Sets the currently active angleset.

inline virtual void SetCell(Cell const *cell_ptr, AngleSet &angle_set): For cell-by-cell methods or computing the residual on a single cell.

virtual ~SweepChunk() = default

void ZeroDestinationPhi(): Zero the portion of the output flux moments vector corresponding to the groupset for this sweep chunk.

inline void ZeroDestinationPsi(): Sets all elements of the output angular flux vector to zero.

inline void SetBoundarySourceActiveFlag(bool flag_value): Activates or deactives the surface src flag.

inline bool IsSurfaceSourceActive() const: Returns the surface src-active flag.

Public Members

std::vector<MomentCallbackFunc> moment_callbacks: Functions of type MomentCallbackFunc can be added to the moment_callbacks vector and these can be called from within functions taking a LBSGroupset instance. The intention is that this function can be used as a general interface to retrieve angular flux values
