Structured hex: extrude, revolve, sweep and mapped all-hex meshing (M5) (#40)
* Structured hex meshing: multi-level extrude and revolve, one-to-one sweep, mapped blocks (M5) modelcraft_mesh::hex::hex_mesh meshes a face-tagged boundary surface with hexahedra by the first structured method that fits: a straight or rotational multi-level sweep (imprinted cross-section arrangement, cuts at reflex corners, mapped/annulus/free regions), a one-to-one sweep through rings of linking faces (least-squares affine layers with residual correction), or a mapped logical cube (trivariate transfinite interpolation). Interval assignment couples shared curves; boundary quads carry B-rep face tags; the certified validity gate, a tiling check and a fidelity check guard the output; hex20 mid-edge nodes go onto the faces. Shape::face_surfaces exposes the analytic face surfaces; the corpus runner gets a structured hex column. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * mesh.hex.generate: structured hex meshing as a command Meshes one body, every body of the open design or an imported surface, replaces the mesh, tags element faces with the B-rep faces (so sets by geometry resolve) and reports per body the method, counts and quality. The quality pass certifies each element once and feeds the validity gate (quality::validity_gate_checks). Shape::size gives the cached body size for defaults instead of a full measure. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Hex: disk O-grids, convex interval cost, early size guard, hex20 corpus column Smooth single-loop sections (cylinders, tori, vases) get a butterfly O-grid instead of the free mesher; interval assignment raises counts by the squared relative error so equal sides share increments evenly; a mesh far beyond the element limit is refused before any work and mapped limits are no longer swallowed. The corpus reports hex8 and hex20 quality. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Catalogue: structured hex commands ready (mesh.hex.sweep, mesh.hex.mapped, mesh.hex.generate) mesh.hex.sweep and mesh.hex.mapped run mesh.hex.generate with the sweeping methods or the mapped one; mesh.hex.generate is the sweep entry's related command. The planned M6 octree entry moves to mesh.hex.octree (its icon renamed with it). docs/features.md regenerated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Docs: structured hex literature (B8), architecture, roadmap, parity; corpus hex column Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Hex: simplify review fixes Prepare each sweep frame's cross-section once (arrangement, cuts, fill) and reuse it across refinement retries; candidate frames come from one setup pass. Edge triangles come from the feature edges, layer counts go through size::edge_divisions, sweep residual weights are computed once per node, flux shape functions live on the stack, and the arrangement's exact side test and distances serve the region probe. The engine takes the boundary options mesh.tet.generate takes and names unnamed faces by index like it; the corpus hex20 run reuses the winning method; the mapped entry lists mesh.hex.generate too; the octree icon is redrawn under its new id.

1D elements I: trusses (rod2, rod3), point masses, rotary inertia, springs and dashpots (#38)
* Model, fem and decks: point masses, rotary inertia, springs, dashpots and rod3 trusses Model: PointMass and Spring definitions (spring | dashpot; to ground or two-point; along a degree of freedom, a vector or the line of the ends) on a set or reference point, resolved per node; ElementKind::Rod3. fem: rod2/rod3 truss kernel on Basis::Line2/Line3 declaring ElementDofs (translations). Decks: Abaqus T3D3, MASS, ROTARYI, SPRING1/2/A, DASHPOT1/2/A; Nastran CONM1, CELAS2, CDAMP2; LS-DYNA ELEMENT_MASS/INERTIA and ELEMENT_DISCRETE; what a format cannot take is reported. Commands model.mass.* and model.spring.*. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Implicit solver: trusses, point masses, rotary inertia and springs on the DofLayout Trusses declare their translations like solids; point masses, inertia and springs ask the layout for the kinds they need at their nodes (translations, rotations), and reference points they use get six degrees of freedom. The matrix pattern takes rows for those points; dashpots are ignored with a warning. Existing results are bit-identical (hash-checked).

Boundary surface preparation (weld, manifold/orientation, exact self-intersection, feature edges) and mesh.surface.check (#15)
* mesh: boundary surface preparation (weld, manifold and orientation checks, exact self-intersection, feature edges) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * engine: mesh.surface.check on an open design's body or an imported surface Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * engine: struct-init the test session Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * surface: weld at an absolute distance too; the engine welds CAD tessellations at twice SolidCraft's linear tolerance Faces of a SolidCraft tessellation carry their own copies of shared boundary points, which agree only to within the kernel's tolerance (up to ~2e-6 mm on the test corpus). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * docs: surface preparation in the literature survey, architecture and roadmap Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * surface: simplify after review - The weld distance travels with the mesh (SurfaceMesh::weld_distance, set by Shape::tessellate), so every consumer welds a tessellation correctly without opting in. - Exact tests are infallible on predicates::orient2d_projected (shared with generic_orient2d), and compute each vertex's plane side once per pair with an early reject. - One Box3 for the weld, the BVH and shells; a Half struct for edges; the weld's two lookups share one loop, with chained grid cells; cached normals for feature edges; shared parameter helpers.

Element quality metrics and the certified validity gate (mesh.quality) (#12)
* mesh: element quality metrics and a certified Jacobian validity check Bernstein-form Jacobian determinants for tet4/tet10/wedge6/hex8/hex20, certified by bounds and subdivision (Johnen-Remacle-Geuzaine 2013); Shewchuk 2002 tet metrics, Knupp 2001 hex/wedge/quad metrics; quality report and the validity gate meshers run on their output.
