Rename the project to FieldCraft
Crates fieldcraft-*, binaries fieldcraft and fieldcraft-cli, the .fieldcraft file (format tag fieldcraft/1, manifest fieldcraft.json), FIELDCRAFT_* environment variables, the MCP server name, egui widget ids (fc_*), the app icon document FieldCraft.icon and its generated family, docs and licences. No compatibility shim: no files of the earlier name exist. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm |

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 <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. Control protocol, architecture, ROADMAP, AGENTS and ATTRIBUTION updated; THIRD-PARTY-LICENSES.txt with craft-ui and rfd. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> 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 <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.

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.

mesh.block: mapped hex, tet and wedge blocks with curved edges; solve.probe at points
A structured mesh of a six-sided block from its corners, with circular and elliptical edges (Gordon-Hall transfinite interpolation), grading, named faces, edges and vertices as geometry tags, and joining to the existing mesh face to face (refused otherwise). solve.probe takes "at" points and reports the nearest node with a result.

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.

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).

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

Implicit solver: reference points, couplings, moments, wedge6 (M4) (#26)
* fem: wedge6 element (triangle × interval, 3 × 2 points), patch and cantilever tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * solver: reference points, kinematic and distributing couplings, moments by constraint elimination Coupled reference points get six degrees of freedom; kinematic couplings are rigid links, distributing couplings least-squares interpolation constraints. Every constraint row and prescribed value is eliminated master-slave (Abel-Shephard pivot choice), so the reduced matrix stays SPD; no coupling gives the old elimination bit for bit. Verified: rigid motion of a coupled block, clamping through a point, distributing tension vs pressure, bending and tube torsion. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * engine: reference point results in solve.static and solve.probe Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * docs: couplings, moments and wedge6 in the solver docs, literature and roadmap Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * solver: simplify constraint elimination and reference point plumbing Rows combine by one sort; T_f transposed once; K and M reduced in one pass on a shared pattern; prescribed motion computed once; reference point loads and BCs go through Resolved like node ones (Mesh::label_dofs); one dof-direction rule; StepResult::locate for probes; dead Csr::restrict removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * solver: refuse oversized reductions before allocating them A held distributing coupling point makes a dense (3N)^2 block; estimate it from the constraint rows and refuse it against the factorization's memory budget with a clear message, before anything is built. Other reductions with dependents count their entries first (stopping at the budget) and reserve fallibly.

Implicit solver: fem kernels (tet4/10, hex8, hex20), sparse Cholesky, block Lanczos, solve.* commands (M4) (#23)
* Renumber the layer table for solver crates: fem at L1, solver at L2, fsi at L3 L0 model -> L1 geometry, mesh, fem, decks, render -> L2 solver (explicit, lbm later) -> L3 fsi (later) -> L4 doc -> L5 io -> L6 engine -> L7 ui-egui, mcp -> apps. UI_MIN_LAYER moves to 7, the testkit sits above it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * modelcraft-fem: element kernels for tet4, tet10, hex8 (full, incompatible modes), hex20 (full, reduced) Shape functions, Gauss and conical-product quadrature, stiffness, consistent and HRZ-lumped mass, body forces, consistent pressure loads on faces, integration-point stresses and their least-squares extrapolation to nodes, isotropic and orthotropic elasticity. The element table is one row per kind, so wedges, shells and beams are added locally. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * modelcraft-solver: linear static and frequency analysis with an analytic verification suite Assembly from the resolved model on the node graph, boundary conditions by elimination, consistent pressure, gravity and body-force loads, nested-dissection ordering, sparse up-looking Cholesky with a factor-size cap, reactions, integration-point and nodal-averaged stresses, von Mises; shift-invert block Lanczos with full reorthogonalization for natural modes, participation and effective mass. ADR 0001 records the own-linear-algebra decision (determinism, wasm). Verified against closed forms: displacement and traction patch tests for every element, cantilever tip deflection (Timoshenko) with convergence rates, Lamé cylinder, Kirsch hole (Kt -> 3), cantilever and free-free beam frequencies with six rigid-body modes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Engine: solve.static, solve.frequency and solve.probe; results kept in the session Results are stored per step, restored on a failed command and cleared when the model changes. Caps (degrees of freedom, factor entries, Lanczos vectors) may only be lowered; hostile parameters are tested against a solvable session.
