Detailed Description

template<rowsize e2p_rs = NonUniformSize>
struct DNDS::Geom::InterpolateGlobalResultT< e2p_rs >

Result of distributed interpolation with globally-unique B entities.

Given A→C cone (global C indices, A is ghosted via A→C→A), creates globally-unique B entities (faces or edges) with ownership resolution.

Outputs

parent2entity: A→B mapping in global B indices. Father = local A, son = ghost A. Slot ordering matches element topology: slot j is face/edge j as defined by Element::ObtainFace(j)/ObtainEdge(j). Some son entries may be UnInitIndex (fully-ghost B not resolved by the push protocol — resolved later by the caller's ghost B pull).
parent2entityPbi: Parallel to parent2entity. One NodePeriodicBits per (A, B) slot — the uniform XOR between A's sub-entity node-pbi and B's stored entity2nodePbi. To get B's node coords in A's frame: apply parent2entityPbi to entity2nodePbi, then GetCoordByBits. For faces, this is at most 1-bit (a face crosses one periodic boundary). For edges, can be multi-bit (e.g., P1|P2 for a corner edge). Zero for the first parent. Empty if not periodic. Computed locally — no MPI push needed (depends only on cell2nodePbi and entity2nodePbi, both available after Step 2b).
entity2node: B→C mapping in global C indices. Father-only (owned B). Node ordering is from the first-discovered parent's ExtractFaceNodes/ ExtractEdgeNodes call — this is the entity's own canonical ordering.
entity2nodePbi: B→C pbi. Father-only. Parallel to entity2node. Pbi from the first-discovered parent's perspective (the entity's own frame). Other parents' perspectives differ by parent2entityPbi. Empty if not periodic.
entity2parent: B→A mapping in global A indices. Father-only. Variable-width: 1 (boundary) or 2 (internal) for faces, 1..N for edges. Complete under A→C→A ghosting (all parents sharing any C-vertex with a local A are present as ghosts, so all parents of any locally-visible B entity are enumerated).
entityElemInfo: Per-entity element info. Father-only.

Ghost B entities

NOT included. Use evaluateGhostTree(A → A2B → B) to pull them, then BorrowAndPull on entity2node / entity2nodePbi / entityElemInfo. parent2entityPbi for ghost A parents is already populated (the push only carries the global B index; pbi is local). After ghost B pull, entity2parent for ghost B can be obtained via Inverse(parent2entity) or by ghost-pulling entity2parent itself.

Template Parameters

e2p_rs Row-size of entity2parent (NonUniformSize = variable, 2 = fixed for faces, etc.).
