demo video: a horizontal cantilever, checked against beam theory
The demo used the corpus I-beam, which is extruded along z and so stood upright. A new corpus part, cantilever-i-beam, is the same section on the YZ plane extruded along x, web upright: a sweep along a horizontal axis for the meshers, and a cantilever that bends downward on screen. The i-beam part is unchanged (its corpus row and the meshing tests keep it). The demo clamps it at x = 0 and loads the free end with 1000 N in -z through a kinematic coupling, and now checks the solution against beam theory and stops when it is off: tip deflection (bending plus shear) within 3 %, root bending stress (stress_xx along the top flange, extrapolated to the root, nodes from the Abaqus deck) within 2 %. docs/meshing/corpus.md regenerated with the new part.

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 <[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]> 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 <[email protected]> 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.

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 <[email protected]> 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 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * engine: struct-init the test session Co-Authored-By: Claude Opus 5.5 <[email protected]> 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).
