Sample

Sample represents one observation. It contains Feature identifiers among (all optional):

• scalars: name → value

• meshes containing:

  • nodes: mesh node coordinates, that can be located:

    • in different bases

    • in different zones in each base

  • fields, arrays that can be located:

    • in different bases

    • in different zones in each base

    • in different locations in each base/zone among: Vertex, EdgeCenter, FaceCenter, or CellCenter

Key APIs include:

• Feature accessors: get_scalar(), get_field(), get_nodes()

• Feature updates: add_scalar(), add_field(), set_nodes(), and high-level identifier-based updates

• Discovery: get_all_features_identifiers() or get_all_features_identifiers_by_type() to list all available features with their context
