souxmar

Single pipeline, three surfaces

The same C++ engine drives the CLI, the Python library, and the desktop app. Whatever the AI agent does, you can also do directly.

Agentic AI chat, BYOK

Bring your own Anthropic / OpenAI / Ollama key. Your geometry never leaves your machine unless you ask it to.

Plugin ABI frozen at v1.3

Third-party meshers, solvers, readers, and writers compile once and run on every souxmar release in the 1.x line.

Signed auto-update

ed25519-signed release manifests + atomic apply + one-command rollback. Trust path documented top to bottom.

What is souxmar?

souxmar is an open-source CAE platform — CAD modelling + mesh generation + finite-element + CFD + post-processing — wrapped in a cross-platform desktop app with an agentic AI chat that can drive the entire pipeline.

The free tier is the full product. You bring your own AI provider key (or run locally against Ollama), your own compute, and you owe us nothing. The Pro tier adds managed AI + cloud sync; see the business-model page.

Why it's different

Local-first. Your geometry, your simulation results, your AI prompts — all on your machine unless you opt into Pro features. No telemetry beyond optional crash reports.

Three peer surfaces. The desktop app, the CLI (souxmar), and the Python library (pysouxmar) all sit on top of the same C++ engine. The AI agent uses the same tool surface anyone can call directly.

Plugin-extensible at the ABI. A stable C ABI (v1.3 frozen final for the 1.x line) lets meshers, solvers, readers, and writers ship as .so/.dylib/.dll files. Drop one in ~/.local/share/souxmar/plugins; it works on every souxmar release.

Auditable trust path. Releases are signed with an ed25519 key whose rotation procedure is documented in ADR-0014; the embedded trust store + the souxmar update flow are documented in the updates guide.

Status

Public alpha — v0.9.0. The plugin C ABI is frozen final at v1.3. The agent tool contract is frozen final at v1 with 18 tools. The desktop workbench shell scaffolds but the viewport / chat / inspector wait on the souxmar-bridge FFI crate (landing across Sprint 13). The CLI and Python paths are fully wired.
