solver, model, engine: linear buckling steps
Procedure::Buckle {modes, shift}: the step's loads as a linear preload, K_σ from its stresses,
and (K + λ K_σ) φ = 0 by block Lanczos in the K inner product: K⁻¹(−K_σ) on Cholesky without a
shift, the buckling transformation (K + σ K_σ)⁻¹ K on LDLᵀ with one, whose inertia counts the
load factors below σ (Grimes–Lewis–Simon 1994). Lanczos gains an operand and an eigenvalue map
(defaults keep frequency steps bit for bit) and reports converged negative eigenvalues. Results
are frequency results with a `buckling` part; modes display with their load factor.
solve.buckle (in the Static drop-down); Abaqus *BUCKLE, Nastran SOL 105 and LS-DYNA refuse it by
name. Euler columns of hex20 within 0.18 % of Engesser's load.

model: contact pairs, general contact and Coulomb friction, mapped by the deck writers
Contact definitions on face sets: a pair (each surface's nodes against the other's faces), general contact on a surface (self contact) or on every exterior face of the solids; Coulomb friction with static and kinetic coefficients and an exponential decay, a penalty scale and the choice to adjust or refuse initially penetrating nodes, validated with caps. Rigid walls of explicit steps gain friction. The check wants solid faces on contact surfaces; sets used by a contact cannot be deleted. fem::contact: the closest point of a triangle (Ericson) or a bilinear quadrilateral (projected Newton) to a point, and a bucket grid of face boxes for the global search, deterministic and bounded. Commands interaction.contact.pair, .general, .edit, .delete and .find (the touching parts of the mesh, with face sets and pairs made of them); contacts in the model browser. Abaqus writes *SURFACE INTERACTION with *FRICTION (exponential decay), *CONTACT PAIR and general *CONTACT; LS-DYNA *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE and _SINGLE_SURFACE with FS, FD, DC; Nastran refuses contact by name. The implicit solver refuses contact by name (M7); the explicit solver refuses it until the next commit.

Tet mesh quality: one validity criterion, Delaunay refinement, ODT, Klingner–Shewchuk, tet10
The end-to-end demo met a raw-CDT sliver that the validity gate accepted (exactly positive) and the solver refused. Now: - One validity criterion, `fieldcraft_model::admissible_jacobian` (normalized Jacobian above 1e-12), used by the implicit solver (fem `positive_inverse`), the explicit tet4/hex8 kinematics and the mesh gate, which proves it on the whole element (tet4: the solvers' own Jacobian; curved kinds: a Bernstein floor), so whatever passes the gate passes the solvers. - CDT rounding repaired by flips on the rounded mesh (Diazzi et al. 2023 §5.1) instead of the ±2-ulp nudge. - `fieldcraft-mesh::tet`: a mutable tetrahedral complex whose every change is a checked replacement (positive and admissible tetrahedra, faces matched with opposite orientation) with an exact undo log; edge removal (Klincsek), multi-face removal, Delaunay insertion with boundary faces, edge collapse; a curvature- and thickness-graded size field; constrained Delaunay refinement with encroachment splits; ODT smoothing; the Klingner–Shewchuk schedule; boundary vertices moved onto the exact B-rep surfaces at the end; tet10 with mid-edge nodes on the geometry. - `mesh.tet.generate` gains size, order, quality, quality_target, curvature_angle, grading, max_passes, max_points and reports the CDT's and the mesh's quality; `solve.probe` takes a set and reports its largest von Mises stress. - Oracle cases filleted-bracket-fillet-stress(-coarse): the fillet's peak von Mises stress on tet10 meshes of 2k and 13.5k elements, 213.3 MPa (a four-level study stays within 1.8%); the CDT cases keep the raw tetrahedralization. - Corpus quality columns: all 20 valid parts mesh and pass the gate.

engine: mesh.hex.octree command
Replaces the mesh with the octree all-hex mesh of a body, an imported surface or every body of the open design, and tags boundary element faces with their B-rep faces so sets by geometry resolve. Size, tolerance, refinement depth, element cap, attempts and optimiser sweeps are validated and capped; the element cap defaults to the session limit (`Limits::max_hex_elements`), which the hostile-params test keeps small. Body input and face tagging are shared with mesh.hex.generate. The catalogue's Automatic Hex entry is ready.

mesh.hex.blocks: one conforming hex mesh of a design split into blocks
Meshes the open design's bodies (or the listed ones) as the cells of one conforming all-hex mesh with one size and tessellation tolerance for all; elements carry their cell's body, boundary faces its B-rep faces. A cell that is no block, or cells that touch without sharing whole faces, is an error naming the bodies. Catalogue entry with its VectorCraft icon, the MCP mesh tool's hex_blocks method, docs/features.md.

solver: nonlinear static analysis by Newton–Raphson with automatic increments
solve.nonlinear follows a nonlinear static step in load increments: dead loads and prescribed displacements ramp with the load factor, a pressure follows the deformed faces (its load stiffness symmetrised so the supernodal Cholesky stays), the consistent tangent is refactored every iteration with an optional line search, and an increment converges on force, displacement and energy together. Increments start from the extrapolated last one, grow after fast convergence and are cut back on inversion, a non-finite or growing residual, an indefinite tangent or too many iterations; the step stops cleanly at the minimum increment, the increment cap or the Newton iteration limit. Elements are assembled in parallel in label order (same bits on any thread count). Results carry Cauchy stress, logarithmic strain, the increment history and a displacement frame per increment, which results.frame and the results panel show. Trusses, shells, beams, plane stress, incompatible modes, temperature and centrifugal loads are refused by name; couplings warn that they stay linear.

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.

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.

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

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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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.

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. Step commits before the rebase onto the DOF framework: branch explicit-x2-steps.

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. Benchmark: Schäfer–Turek 2D-1.

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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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 <noreply@anthropic.com> 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.
