Typedef documentation

using tk::UnsMesh::Chunk = std::tuple<std::vector<std::size_t>, std::vector<std::size_t>, std::unordered_map<std::size_t, std::size_t>>

Alias for storing a mesh chunk

The first vector is the element connectivity (local mesh node IDs), the second vector is the global node IDs of owned elements, while the third one is a map of global(key)->local(value) node IDs.

using tk::UnsMesh::Edge = std::array<std::size_t, 2>

Edge: node IDs of two end-points

tk::UnsMesh::UnsMesh() explicit

Constructor without initializing anything
