Detailed Description

template<rowsize p2e_rs = NonUniformSize, rowsize e2n_rs = NonUniformSize, rowsize e2p_rs = NonUniformSize>
struct DNDS::Geom::InterpolateResultT< p2e_rs, e2n_rs, e2p_rs >

Result of interpolating (extracting) sub-entities from parent→node connectivity.

Given parent→node (e.g., cell→node), Interpolate creates intermediate entities (e.g., faces or edges) by extracting sub-entities from element topology, deduplicating by sorted vertex comparison, and building both parent→entity and entity→node adjacencies.

All indices are local (0-based within the input arrays). No MPI communication is performed — the caller is responsible for providing a complete view (local + ghost cells) and for subsequent ownership resolution / ghost exchange. Result of local (rank-only) sub-entity interpolation.

Given parent→node (e.g., cell→node), Interpolate creates intermediate entities (e.g., faces or edges) by extracting sub-entities from element topology, deduplicating by sorted vertex comparison (+ optional matchExtra for periodic), and building both parent→entity and entity→node adjacencies.

All indices are local (0-based within the input arrays). No MPI communication is performed. The caller provides a complete view (local + ghost cells) and handles subsequent ownership resolution / ghost exchange.

Ordering guarantees

parent2entity[iParent][j] corresponds to sub-entity j of parent iParent as defined by query.numSubEntities / query.describe / query.extractNodes.
entity2node[iEnt] stores nodes in the order extracted by the first parent that created entity iEnt. Later parents that find the same entity do not alter the node order.
entity2parent[iEnt] lists parents in discovery order (first parent first).

Template Parameters

p2e_rs	Row-size of parent2entity (NonUniformSize = variable).
e2n_rs	Row-size of entity2node (NonUniformSize = variable).
e2p_rs	Row-size of entity2parent (NonUniformSize = variable).
