Survey of about 75 papers on robust predicates, Delaunay tetrahedralization, boundary recovery, quality improvement and hexahedral meshing, with verified DOIs and the licence of every associated code base. Architecture and roadmap now name the chosen methods (robust CDT after Diazzi et al. 2023; octree-dual all-hex first). ADR 0001 adds the licence findings and the test-geometry rule.

# 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 | Robust adaptive-precision predicates; weld, closed/manifold/orientation checks and feature edges on the tessellated boundary; mesh quality metrics | next |
|
||
| 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 | planned |
|
||
| M8 Post-processing | Results display: deformed shape, contours, probes | planned |
