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.
