Module mesh 

Layer 2 — the finite-volume mesh: cells, faces, boundary patches, and geometric metrics. Finite-volume mesh layer: topology and geometry.

This module holds the flat, cache-friendly mesh representation the FV operators run on. It contains:

• FvMesh — the mesh itself (cells, faces, owner/neighbour connectivity, cell volumes [m³], face-area vectors [m²], and cell/face centres [m]), plus FvMeshBuilder to assemble one incrementally.
• BoundaryPatch / PatchKind — boundary-patch descriptors.
• ami — arbitrary-mesh-interface (non-conformal periodic / cyclicAMI) face-overlap weighting and AmiCoupling representation.
• RegionInterface — a face-to-face coupling map between two regions’ patches (used by conjugate-heat-transfer solvers).
• MeshError — the errors raised during mesh construction and validation.

It stores only the data required by the operators; the OpenFOAM polyMesh → primitiveMesh → lduMesh inheritance chain is not reproduced.
