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.

Hybrid (mixed u–p) solids: hex8 and tet10 with a constant pressure, hex20 with a linear one (#49)
The isotropic elasticity splits into D_dev + K m mᵀ; an element-wise discontinuous pressure is condensed out (p̂ = K M⁻¹ Gᵀ u), leaving K_dev + K G M⁻¹ Gᵀ (Hughes §4.3–4.5). Q2–P1disc and P2–P0 are inf-sup stable; Q1–P0 does not lock; tet4 and wedge6 still lock and are refused, as are orthotropic materials (named at the section). ElementDofs counts the condensed pressures. Verified: element patch, rigid modes and totals for every hybrid kind, a block in uniaxial strain at ν = 0.4999 (exact), Lamé's cylinder in plane strain at ν = 0.4999 (hex20 1e-5, tet10 1.3e-3, hex8 2.5e-3 vs the locking displacement hex8 at −80 %). Every non-hybrid result of the test suites hashes identically before and after.

FEM foundation B: heat transfer and thermal stress (solids, 2D, explicit), coupled temperature–displacement, solve.heat (#45)
* Heat transfer and thermal stress: thermal materials, temperature BCs, heat loads, heat transfer and coupled temperature–displacement steps, solve.heat
Model: Material.thermal (conductivity, specific heat, expansion, isotropic or
per axis; reference temperature), BoundaryCondition::Temperature (dof 11),
loads SurfaceFlux, Convection, HeatSource and Temperature (a field in static
steps), procedures HeatTransfer { transient (θ-method) } and
CoupledTemperatureDisplacement; checks for missing conductivity/specific
heat/expansion. fem: heat conduction kernels (conductivity, capacity,
source, face flux/film, heat flux) on the DofLayout (one T per node), thermal
strain load and stress D(ε − ε_th) for every solid formulation incl.
incompatible modes. Solver: steady and transient heat transfer, thermal loads
in static steps, coupled steps (exact one-way coupling). Engine: solve.heat,
temperature/heat-flux result fields, probes. Decks refuse heat transfer by
name. Analytic verification: slab, source+convection/flux, thick cylinder,
erfc semi-infinite solid, free/constrained expansion, bimetal strip, coupled
step.

* thermal: strains in 2D elements and explicit dynamics
Plane::thermal_load and stresses_with for plane stress (εzz free), plane
strain (σzz = −D₃·ε_th) and axisymmetric elements, incompatible modes
included; the solver's 2D kernels take them. Explicit dynamics turns a
step's temperature loads into a per-element thermal strain rate (reached
linearly over the step) subtracted from each strain increment, so it feeds
J2 and Johnson–Cook updates. Verified: free expansion in every 2D theory
and element, a biaxially held plate, an explicit free bar (ΔL = αΔT L,
stress-free) and a clamped bar at −EαΔT, capped at the yield stress with
perfect plasticity.

Craft-family shell, native file dialogs, samples and one-click Solve (#46)
* Native file pickers, background opening, drag and drop and recent files Open (models, SolidCraft designs and tagged meshes in one picker), Save, Save As, Write Deck and Recover go through the host's file pickers (rfd in the desktop app, injected as Services so the UI crate stays portable and tests answer them). Files open on a copy of the session in a worker thread and replace it only on success; files dropped on the window or named on the command line open the same way. A recent-files list, an unsaved-changes prompt, Cmd/Ctrl+O/S/Shift+S. Programmatic calls never open a picker: ui.start opens the form. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Samples and one-click Solve: results reachable from the window file.sample {name} opens a ready-to-run sample (the two parts, the cantilever with static and frequency steps, the bar impact) in place of the model; solve.run solves every step in order. Help > Samples, the empty viewport's start screen and the Tools > Samples entry open them (asking first over unsaved changes); Solve runs in the background like a file opening and the Results tab comes up. --sample [parts|cantilever|impact] on the command line. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * The Craft-family shell: title bar, workspace ribbon, browser, context panel, timeline The window now follows SolidCraft's and VectorCraft's layout and themes: - title bar with the mark, quick actions (File menu, save, undo, redo, Solve, search, theme, help), the model's document tab and the version; integrated under the macOS traffic lights, own caption buttons and resize zones elsewhere (titlebar.rs); - workspaces (Prepare, Model, Analysis, Results) with their tabs, and panels of icon buttons whose labelled drop-downs list the whole catalogue, coming-soon entries greyed with their milestone; panels collapse, then go into a » menu, when narrow; - the browser: geometry and mesh with eye toggles, definitions with counts, results; - no permanent Commands list: command search (S, Cmd/Ctrl+K) and a command line; - the context panel on the right only with context: the command form, results controls, the selected definition's properties with Edit and Delete; - navigation bar and orientation gizmo in the viewport; the journal timeline at the bottom with undo positions; - SolidCraft's light and dark tokens; craft-ui (IconButton, Tab, WidgetPalette). Menus and the search are view state (ui.set {menu, palette}), so captures show them. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Shell polish, docs and licences Menus painted as the family's (flat File menu with recent files, decks and samples), the legend sized to its text, two-line panel labels inside the ribbon, glyphs the UI font has, offscreen captures without fade-in, ui.start runs in-window file actions (samples, recover, solve) but never a native picker, ui.select. Control protocol, architecture, ROADMAP, AGENTS and ATTRIBUTION updated; THIRD-PARTY-LICENSES.txt with craft-ui and rfd. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Title bar mark from the application icon; fluid steps and domains in the shell The title bar draws the app icon's bracket (assets/app-icon/icon-small.svg's faces) as SolidCraft draws its mark; the window keeps its title-bar flags after the rebase. solve.run solves fluid steps too (solve.fluid); the browser lists fluid domains. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Simplify: cached per-frame data, one command per timeline roll, workspace setters - Icon textures are kept per pixel size (the shell draws several sizes a frame; the cache used to clear on every size change and rasterise again). - Opening a model or recovering one starts from an empty session instead of copying the current one; the replaced session is freed off the window thread. - Element counts, timeline items, search results and the selected definition's properties are cached until what they show changes; timeline tooltips are built on hover; long lists in properties are summarised. - edit.undo and edit.redo take a count: a timeline click is one command. - solve.run dispatches on the step's procedure (no string round trip) and reports its name. - The workspace and tab change together through UiState::select_tab/select_workspace (ui.set {workspace} alone now sticks); no per-frame syncing. - One busy guard, Kind::verbs, a fit flag for background jobs, ModelApp::home_view, the title bar's actions as an enum, dead code removed. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Title bar: Solve and tools at the right end; no traffic-light inset in full screen The owner's feedback on the title bar: Solve, search, theme and help sit at its right end before the version; on macOS the left group (mark, name, quick actions) moves into the traffic lights' room in full screen, where there are none, and back when leaving it. The layout is a pure function (bar_layout) tested for both states, narrow windows and custom caption buttons. ui.fullscreen {on} for agents. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Caps labels in Inter SemiBold egui has no bold weight of its default font, so the ribbon's tabs and panel labels, the workspace switcher and its menu, menu headings, the browser header, the context panel's headers and the Solve label were thin, especially in the light theme. They now use a label font family: Inter SemiBold 4.1 (SIL OFL 1.1, unmodified, fonts/OFL.txt, ATTRIBUTION.md), with egui's fonts as fallback, installed with the theme on the live and offscreen contexts. theme::label_font falls back to the default font until the family is bound (fonts take effect from the next pass), so nothing can panic. Panels widen to their label's longest word.

simplify: joining in modelcraft-mesh::join, shared label helper, run_script returns step outputs
Weld and face-to-face check move from the mesh.block command to modelcraft_mesh::join (bounding-box-limited weld, grid-binned hanging-node test), for node merging and imports to reuse. mesh.block and mesh.tet.generate share fresh_labels. The block map evaluates each edge curve once per lattice parameter; vector helpers come from vec3; tet10 and hex20 mid-side nodes follow ElementKind::edges. Session::run_script returns each step's output, which the oracle reads instead of its own loop.

Fast PR CI: small hostile-test caps, heavy tests in a separate job (#43)
* test: hostile-params test runs under small session work caps Session gains Limits, the defaults of mesh.tet.generate's max_steiner and max_tets (production values unchanged; a parameter still overrides them; file.open keeps them). The registry-wide hostile-params test runs on sessions with small caps, so the needle-triangle tessellation it meshes is refused at once instead of meshing to the 50k Steiner cap: the engine test binary drops from ~350 s to ~20 s locally. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * ci: move heavy tests to a heavy job on main, nightly and on demand Four slow tests are #[ignore = "heavy: ..."] (every corpus recipe, the cantilever convergence study, the explicit-vs-modal cantilever period, the generic-predicate rational cross-check); fast representative tests of each area stay in the PR gate. cargo xtask test --heavy runs every ignored test (benchmarks included) and the doc tests; cargo xtask test and ci run the rest without the doc tests. The new heavy CI job runs it on pushes to main, nightly and on workflow_dispatch. Branch jobs restore main's rust cache and no longer save their own. AGENTS.md documents the rule. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * test: the three slow LBM verification cases run in the heavy job The Stokes-drag sphere array, the staircase-pipe convergence study and the developing-channel case are heavy (21 s, 11 s, 6 s alone); plane Poiseuille, Couette, Taylor-Green, reproducibility and the stability limits stay in the PR gate.

Explicit X2: large deformation, J2 and Johnson-Cook plasticity, damage and erosion (M10)
- model: materials gain solver-neutral plastic (bilinear isotropic/kinematic, hardening table, Johnson-Cook with adiabatic heating), damage (Johnson-Cook D1-D5) and erosion (plastic strain); explicit steps gain nonlinear_geometry (default on) and stress_rate (jaumann | green_naghdi). - fem: rotation (Hughes-Winget, Flanagan-Taylor), plasticity (radial return, capped bracketed Newton for Johnson-Cook, damage; the update takes the mechanical strain increment so thermal strains can be subtracted), closed-form hex8 gradients for deformed configurations. - explicit: updated Lagrangian hex8/tet4, per-element material state, erosion with reported energy, plastic work in the energy account. - solver: warns that the linear solver uses the elastic constants of plastic materials (results hash-identical). - decks: Abaqus *PLASTIC (+ Johnson-Cook keywords), Nastran MATS1/TABLES1, LS-DYNA *MAT_PLASTIC_KINEMATIC / *MAT_PIECEWISE_LINEAR_PLASTICITY; what a format cannot express is reported as Unsupported. - engine: model.material.plasticity, model.material.damage (catalogue ready), explicit element probe, eroded elements in the solve summary.

Lattice Boltzmann flow on the CPU: model, solver, engine (M12) (#36)
Model: Newtonian fluid materials; fluid domains (box, spacing, conditions on the box faces, obstacle bodies with conditions on their named faces, initial velocity, body acceleration); fluid steps with caps. Deck writers refuse fluid steps; a fluid-only model needs no mesh in model.check; one step selector (Model::select_step) for every solver. New L2 crate modelcraft-lbm: D3Q19 two-relaxation-time collision with Guo forcing; halfway bounce-back walls (moving walls after Ladd), slip faces, periodic pairs; Zou–He velocity and pressure faces with the D3Q19 transverse correction; obstacles voxelised from the face-tagged boundary surface with exact predicates and symbolic perturbation; momentum-exchange forces per box face and per B-rep face; unit conversion, automatic time step and Mach/tau limits; bounded runs with frames and force histories. Engine: model.fluid_domain.create/edit/delete, model.fluid_domain.boundary, solve.fluid (obstacles from the open design or imported surfaces, lowerable caps), solve.probe for fluid fields and wall force histories. Fluid Domain, Inlet & Outlet and Lattice Boltzmann toolbar entries are ready. Verification (analytic): plane Poiseuille exact with Λ = 3/16 and second order (2.000) with Λ = 1/4; Couette exact with the wall shear; Taylor–Green decay second order (2.01, 2.00); staircase pipe; Stokes drag of a sphere array within 1.7% of Hasimoto at R = 6; Zou–He channel; mass conserved to round-off; bit-for-bit reproducibility.

FEM foundation A: DofKind/DofLayout, shape-function library with Hessians, solvers on DofLayout (#35)
* fem: DofKind/DofLayout and the shape-function library with second derivatives DofKind (Ux..Rz, T, P), DofSet, ElementDofs (per-node kinds and condensed internal unknowns) and DofLayout: mesh nodes by label, kinds in order, then reference points. basis::Basis covers line2/3, tri3/6, quad4/8/9, tet4/10, wedge6/15, pyramid5, hex8/20/27 with values, first and second natural derivatives (second-order forward AD, fem::jet) and the physical gradients, Hessians and Laplacians with the map's second-derivative term. Tested for Kronecker delta, partition of unity, polynomial completeness, finite differences, affine and curved maps. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * solver, explicit: number degrees of freedom with DofLayout The implicit mesh numbers its unknowns with a DofLayout (mesh nodes by label with the kinds their elements declare, then six per coupled reference point); assembly adds element blocks by (node, DofKind), so a node may carry any mix of kinds; couplings, boundary conditions, loads and results address (node, kind). The explicit system keeps node-major translations, now checked against its layout (NODE_DOFS). Solid formulations declare their ElementDofs. Every static, frequency and explicit result of the solver, explicit, engine and io test suites hashes bit-identically before and after (957 results). docs/fem.md describes the DOF model and the shape-function conventions.

Results display (M4) and offscreen full-UI capture (#28)
* ui.capture: the whole window drawn offscreen and rasterised on the CPU ui.screenshot falls back to it when no frame is presented (hidden window, locked screen), so agents can look at panels and the toolbar. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Draw the open design and imported surfaces in the viewport DisplayMesh keeps node labels on every element primitive (for results), gains add_surface (geometry faces and their boundaries, coincident points welded) and displaced (elements moved by nodal offsets). Bodies are tessellated at a thousandth of their size; meshed models show the geometry as boundaries only. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * results.* commands: deformed shape, contours, mode shapes, animation, reaction sums The results display is session state (ResultsView), set by commands that are not edits. Nodal fields (displacement, von Mises, principal and component stresses; principal stresses in closed form after Smith 1961) and reaction force and moment sums per set. Results kept from an earlier revision stay viewable, marked stale; solve.probe says when a result is stale. The Results tab's display and reaction entries are ready. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Results display: deformed shape, contours with legend, mode shapes and animation, probe, reaction sums The viewport draws the session's results view: elements moved by their nodes' displacements or a mode shape (automatic or given scale), faces split exactly along contour band boundaries into flat-coloured pieces (same on GPU and CPU), a legend with levels and extremes, a results panel whose controls run the results.* commands, a click probing the nearest node (solve.probe), and stale results marked. Solving from the form shows the result on the Results tab. sample::cantilever is a solvable model for tests and demos. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Simplify the results display (review) One Contour in the plot; the results scene reuses scene::build; a solve shows its result through the engine (ResultsView::for_result) and the UI raises the Results tab when a view appears; the plot's scale and contour values are kept across animation frames; design bodies are tessellated once per design; the first content is framed where the display is rebuilt; field_values in one match; probe reuses results::displacements. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Results display for explicit steps: field frames, energy histories The results view works on the engine's step results (static, frequency, explicit): ResultsView.frame and results.frame {frame | time} pick an explicit field frame; the deformed shape (true scale) and contours (element stresses averaged to the nodes, velocity) follow it; animation runs through the frames. The Results panel has a frame slider and plots the kinetic, internal, hourglass and external energies with their values at the frame. sample::impact is a steel bar flying onto a rigid wall.

Model definition: sets by geometry name, materials, sections, couplings, BCs, loads, steps, check (#16)
* model: split nodes and elements into a mesh module (no behaviour change) Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * model: sets by geometry name, materials and units, sections, couplings, BCs, loads, steps and the check Sets bind to persistent geometry names through the mesh's geometry tags (element, element face/edge and node classification) and resolve against the current mesh, so they survive a remesh. Steps list their active loads and boundary conditions explicitly. Model::check names every missing or bad item; Model::resolve gives the writers' view.

Drops the unused `element` fields on DisplayTri/DisplayLine, the unused Mat4::IDENTITY and corner_count, and hoists the line colour out of the raster loop. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * viewport: split GPU geometry into batches within the buffer limit; refuse oversized CPU renders A mesh with a few million boundary triangles made one vertex buffer larger than the device's max_buffer_size (256 MiB under the limits eframe requests), and wgpu's default error handler panicked. Geometry is now uploaded in batches of whole primitives, each at most 128 MiB and the device limit, and all are drawn. A device error handler logs errors and shows them in the status bar instead of panicking. The CPU renderer refuses sizes over 8192 per side or 16 MP, and scenes over 20 million primitives, with an error, and allocates its buffers fallibly. ui.render reports a size out of range instead of clamping it; the CPU viewport fits a large window into the limit.
