A Gmsh tet mesh with every node owned — a static record.

Node rows are ordered the way :class:~cadjoint.fem.tetmesh.TetMesh expects them: boundary corners, then interior corners, then (for order 2) the shared midside block, so points[:num_surface] is the boundary and edge_parents describes the trailing rows.

Attributes

Name	Type	Description
points	np.ndarray	Node positions (n, 3) as meshed (and snapped).
cells	np.ndarray	Connectivity (t, 4) or (t, 10) in meshio order, positive volume.
owned	OwnedNodes	The ownership record the node_map kind consumes.
entity_dim	np.ndarray	Per node, the dimension of the entity Gmsh gave it to (0 vertex, 1 curve, 2 surface, 3 volume).
num_surface	int	Number of leading boundary corner nodes.
num_corner_points	int	Number of corner nodes (excludes midsides).
edge_parents	np.ndarray | None	(e, 2) corner pairs for the midside block, or None for order 1.
max_step	float	The displacement clamp a re-projection should use.
stats	dict	Timings and counts — see :func:gmsh_tet_mesh.
