fem.gmsh.tet_mesh_from_gmsh

fem.gmsh.tet_mesh_from_gmsh(mesh, *, grid=None, points=None)

Wrap a :class:GmshMesh as the FEM layer’s :class:GmshTetMesh — static.

The node layout is already the one :class:~cadjoint.fem.tetmesh.TetMesh documents — boundary corners, interior corners, midsides — so this only attaches the boundary triangles and the frozen base positions.

edge_parents here describes which corners a midside lies between, not a straight-sided construction: the midsides are on the surface. Consumers that read it as a corner-pair table (BC completion, TET10 element assembly) are unaffected. The positions are the seeds; what moves them under a design change is the node_map kind.
