* render: display data from the FE model, orbit camera and CPU rasterizer modelcraft-render (L1, no GPU): DisplayMesh (the unshared faces of solid elements, shells, element edges, line elements, nodes), the orbit camera and a CPU rasterizer with PNG output for headless snapshots, adapted from SolidCraft's render crate. Workspace: egui/eframe/egui-wgpu 0.36 and SolidCraft's patched egui-wgpu from the pinned rev.

Adapted from SolidCraft's ui-egui and app. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * THIRD-PARTY-LICENSES: the desktop app's dependencies Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * docs: control protocol, desktop app in architecture, roadmap and attribution Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * render: simplify the display mesh (sorted face keys over maps, no unused fields) Interior faces are found by sorting fixed-size face keys instead of a BTreeMap of Vecs, edges are deduplicated by sort, and each element's corners are looked up once. 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.

Roadmap
ModelCraft's goal is CAE pre-processing on par with Abaqus/CAE, Nastran pre-processors and LS-PrePost, with hexahedral meshing as the centre of gravity, plus its own linear solver.
| Milestone | Scope | Status |
|---|---|---|
| M0 Foundation | Workspace, quality gates (cargo xtask ci), FE model, command engine with rollback and panic guard, CLI, geometry boundary on SolidCraft's kernel and tessellator |
done |
| M1 Surface preparation | Geometry in: open .solidcraft designs, rebuilt by SolidCraft, with persistent face names (done); face-tagged 3MF files (geometry.import.mesh, docs/formats/tagged-mesh.md, done); the meshing test corpus: 16 SolidCraft recipes and 5 analytic shapes, cargo xtask corpus → docs/meshing/corpus.md (done); exact predicates (Shewchuk adaptive, symbolic perturbation, indirect LPI/TPI, done); weld, closed/manifold/orientation checks and feature edges on the tessellated boundary; mesh quality metrics and the certified validity gate (modelcraft-mesh::quality, mesh.quality, done) |
in progress |
| M2 Tetrahedral meshing | Bowyer–Watson Delaunay, robust constrained Delaunay boundary recovery (Diazzi et al. 2023), Delaunay refinement to a size field, ODT smoothing, Klingner–Shewchuk sliver removal; linear and quadratic tets | planned |
| M3 Hexahedral meshing (core) | Octree/grid dual all-hex (valid on any input), then hex-dominant by tet recombination, then polycube for blocky parts; see docs/meshing/literature.md | planned |
| M4 Model definition | Materials, sections, sets and surfaces, boundary conditions, loads, steps, output requests | planned |
| M5 Solver decks | Abaqus input, Nastran bulk data, LS-DYNA keyword: writers first, then readers | planned |
| M6 Linear solver | Element library, sparse assembly, linear static and modal analysis, verified against analytic solutions | planned |
| M7 Desktop and agents | egui desktop app, control channel, MCP server, browser build | started: desktop app (viewport, model tree, commands, status bar) and control channel |
| M8 Post-processing | Results display: deformed shape, contours, probes | planned |
