Class Documentation

class LBSGroupset

Shared groupset state.

This class is not specific to LBSProblem. It is shared infrastructure used across problem implementations, including discrete ordinates, to carry both generic group-iteration settings and groupset-scoped transport data.

This class remains the sole groupset representation used by the transport solvers, so method-specific groupset data continues to live here.

Public Functions
