* docs: verification and validation against theory, experiments and published benchmarks; fixtures Owner decision 2026-10-13: test against experimental and theoretical data; results published by vendors (e.g. Abaqus benchmark and verification manuals) may be used as cited reference values for our own models of the same problems; once a case matches, its result becomes a fixture so fidelity cannot regress. Commercial products are still never run and their files and text never copied.

ModelCraft
An open-source, clean-room CAE modeling application in pure Rust: geometry to analysis-ready finite element models, with robust tetrahedral and hexahedral meshing, solver decks for Abaqus, Nastran and LS-DYNA, and its own linear static and modal solver. Desktop, browser and AI agents drive the same commands.
Status: early. The workspace, quality gates, the FE model, the command engine and the geometry boundary (SolidCraft's kernel and tessellator) are in place; meshing is next. See ROADMAP.md.
Build
cargo xtask ci # fmt, assets, licences, layers, clippy, tests, wasm
cargo run -p modelcraft-cli -- commands # every command and its parameters
cargo run -p modelcraft-cli -- run script.json # run a command script
Rust 1.95 or later, with the wasm32-unknown-unknown target for cargo xtask ci.
