OpenEnginX (Open-Source Digital Engineering Platform)

Open-Source Next-Generation Digital Engineering & Physical AI Platform
Democratizing high-fidelity 3D Multiphysics, 1D MBSE (FMI), and Physics-Informed AI for engineers, researchers, and makers worldwide.

---

🚀 Key Features

• Code-as-CAD & Auto-Meshing: Parametric B-Rep geometry definition via build123d and automatic boundary-tagged meshing with Gmsh.
• 3D Multiphysics Coupling: Seamless orchestration of open-source solvers (OpenFOAM for CFD, Elmer FEM for Electromagnetics/Thermal, CalculiX for Structural FEA) via preCICE.
• 1D-3D System Co-simulation: Standard FMI 2.0/3.0 support integrating 1D systems (OpenModelica) with 3D field simulations.
• Physical AI & ROM Studio: Distributed DoE parameter sweeps generating high-density field datasets (HDF5/Zarr), training Physics-Informed AI (PINNs/DeepONet/pyMOR), and auto-packaging to deployable .fmu and ONNX runtime models.
• Closed-Loop Digital Thread: End-to-end traceability from requirements (ReqIF/SysML) to operational sensor data (Asset Administration Shell / AAS).
• Self-Healing & Resilient Orchestration: Automated CAD defeaturing and mesh relaxation fallbacks ensuring uninterrupted massive DoE runs.
