A form row's label and its drawn (i) mark show the field's help and unit
on hover. With no unit system a number shows its dimension ("[stress]")

components are captioned (X, Y, Z, or the field's own names such as E1).

Field gains `help`: one or two sentences of our own wording with a
typical value (yield stress: the initial yield, 276 MPa for 6061-T6,
250 MPa for mild steel; hardening modulus explained; and so on), set
next to each field in cmd/forms.rs. Dim::name gives the dimension
("stress"), Field::unit_label the unit or, with no unit system, the
dimension in brackets, and Field::help_text the tooltip with the unit or
where to set the unit system. The JSON Schema description carries the
help too. A test checks every form field has help and every dimensioned
field shows a unit or dimension in every system.

mesh.tet.generate, mesh.hex.*, mesh.hex.blocks and mesh.cells give every
seed on the open design to their meshers, which match them to their own
curves by position, so a seed on an edge two cells share holds in both. The
tet reply gives, per seed, the mesh edges along it. Docs and the roadmap

The seed's spacing becomes size-field samples the field grades from, and
after coarsening its nodes are put on the feature curve and pinned, so the

A seed is matched to a mesher's curve by position (ends and middle within the
two tessellations' tolerance), which also orients its bias. Interval
assignment holds exact seeds, raises minimums and takes free seeds as goals;
an equality, loop minimum or parity it cannot meet with the exact seeds held
names them. Seeded curves get the seed's spacing. Extrude and revolve seed
cross-section curves and the layers of a level interval; sweep and mapped
seed their B-rep edges; cells seed the shared edge once, so both cells keep
it and stay conforming.

The bodies' elements are reflected across a datum plane (or a point and

the design's body at the reflected place (found by volume and centroid, or
named in `as`), its faces with that body's faces under them, so sets by face
name reach both halves. Half a bar meshed hex8 or hex20 and mirrored has the
whole bar's node and element counts and volume, and its bending deflection to
1e-12; tet4 and tet10 mirror valid and conforming.

fieldcraft_mesh::mirror reflects a region's tet4, tet10, wedge6, hex8 and hex20
elements across a plane. The copies list their nodes in reflected order (corners
swapped, mid-side nodes following their edges), so every copy is right-handed;
reflected_faces and reflected_edges give the copy's face and edge over the same
nodes. Copies of the nodes on the plane are merged with the originals through
join::merge_coincident, so the region and its image form one conforming mesh.

Each cell (a body of the open design) gets its own method: structured hex where
one fits (auto falls back to tet and says why), or tet. All go into one mesh.
Cells on either side of a partition are joined: where their element faces
match node for node the nodes are merged; otherwise (hex next to tet, or
different divisions) the two partition faces get a set each and a dual mortar
tie, the reported hex-tet transition. A 40 mm bar cut in half, one half hex,
the other tet, stretches F L / (E A) to 1e-6.

Model::merge_nodes replaces merged nodes by their survivors in elements (node
order kept, so face and edge tags hold) and in set node lists, moves a vertex
tag to an untagged survivor, and refuses a merge that would collapse an

nodes within a distance of a lower-labelled survivor, deterministically.
