Class Documentation

class LBSGroupset

Configuration and runtime state for one contiguous energy-group range.

LBSProblem owns the ordered groupsets. Together they cover every problem group exactly once, from zero through num_groups - 1. Each groupset holds iteration settings and transport data.

Public Functions

explicit LBSGroupset(const InputParameters &params, int id, const LBSProblem &lbs_problem)

explicit LBSGroupset(int id)

LBSGroupset()

void PrintSweepInfoFile(size_t ev_tag, const std::string &file_name)

void InitializeQuadratureCarrier()

Initialize carrier for copying quadrature data to GPU.

void ResetQuadratureCarrier()

Delete carrier and deallocate memory on GPU.

~LBSGroupset()

unsigned int GetNumGroups() const

Return number of energy groups in the groupset.

Public Members

int id

unsigned int first_group

First energy-group index in this inclusive range.

unsigned int last_group

Last energy-group index in this inclusive range.

unsigned int size

Number of groups in the groupset.
