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 |

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.

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.
