jyvikoandClaude Opus 5.5 4ac31d3988 engine: mesh.hex.extrude, hex layers up to a target surface (#400)
The section comes from a set (a 2D mesh or element faces), the mesh already
on the source faces (tagged, or a neighbouring body's boundary lying on
them, whose nodes are shared so the meshes conform), or a fresh quad mesh
of one planar face. Target and side faces project through the tet mesher's
B-rep projection. Replaces the body's mesh like the other meshers, tags the
body's own source, target and side faces, and is on the MCP mesh tool as
hex_extrude.

jyvikoandClaude Opus 5.5 09323ddb45 geometry: meshes go with the bodies a partition change removes (#385)
Deleting, suppressing or editing a partition (or its datum), or cutting a
meshed body, removes the meshes of the bodies that are gone, reported as
replaced, in the same undo step. model.check lists meshes of partition
cells the open design no longer has (a model saved before the cut
changed), and mesh.clear removes them, or the meshes of named bodies.

jyvikoandClaude Opus 5.5 080ff048c6 Engine: crash reports, a log file and bug report drafts (#107)
crash: a panic hook and a locked per-run command journal (adapted from
SolidCraft's crash reports). A panic in a command becomes a report with
the model from before it and the command; one outside commands, or an
unclean exit found at the next start (abort, segfault, a crash in a
graphics driver, a kill: what #248 needs), a report with the model the
journal starts from (autosave, file or a copy) and the commands since,
the last control request and the dead run's log lines. Reports are
bounded, deduplicated by signature and replayable (crash::replay, with
writes confined to a scratch folder). The crash folder follows the
automation temp area in --control and CI runs.

logfile: a small size-rotated file logger behind the log facade.

bug_report: GitHub bug-form drafts. Version, OS and what happened by
default, home folder shown as ~; the command journal only with Share my
session, the model only with Include the model as well; a session too
long for the link becomes a file to attach and the clipboard text.

Commands: diagnostics.crash_reports, diagnostics.crash_report,
diagnostics.bug_report (Tools › Help, with its icon) and
diagnostics.crash_test (FIELDCRAFT_CRASH_TEST=1 only).

A datum point by coordinates, at a mesh vertex, a fraction along a

plane. Datum planes take three datum points or a normal to a datum axis;

geometry.datum.delete with cascade also deletes the partitions that cut
by it. The ribbon shows Datum Plane, Datum Axis, Datum Point and
Partition, each with its own icon; edit and delete leave the ribbon

A symmetry condition (zero normal displacement, zero rotation about the
in-plane axes) on a datum plane normal to X, Y or Z, with its set given or made
of the open design's faces on the plane (a partition's cut faces), so half a
symmetric part is solved as a half. Half a 40 mm bar cut at its mid-width, with
the condition and half the load, bends as the whole bar to 2e-12 with half the
reaction. Inclined planes are refused as not supported yet.

The bodies' elements are reflected across a datum plane (or a point and
normal) with fieldcraft_mesh::mirror and joined on it. The image is tagged as
the design's body at the reflected place (found by volume and centroid, or
named in `as`), its faces with that body's faces under them, so sets by face
name reach both halves. Half a bar meshed hex8 or hex20 and mirrored has the
whole bar's node and element counts and volume, and its bending deflection to
1e-12; tet4 and tet10 mirror valid and conforming.

jyvikoandClaude Opus 5.5 0b6b6c966c Engine: mesh.cells meshes a partitioned part cell by cell
Each cell (a body of the open design) gets its own method: structured hex where
one fits (auto falls back to tet and says why), or tet. All go into one mesh.
Cells on either side of a partition are joined: where their element faces
match node for node the nodes are merged; otherwise (hex next to tet, or
different divisions) the two partition faces get a set each and a dual mortar
tie, the reported hex-tet transition. A 40 mm bar cut in half, one half hex,
the other tet, stretches F L / (E A) to 1e-6.

jyvikoandClaude Opus 5.5 ecf947c090 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.

jyvikoandClaude Opus 5.5 9469ac0853 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.

jyvikoandClaude Opus 5.5 2183fdbe81 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.

5afd1addb9 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.

* 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.

* 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.

* 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.

* 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.

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.

bf325bb234 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.

* 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.

* 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.

* 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.

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.

* 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.

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.

Trusses declare their translations like solids; point masses, inertia and

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).
