Teaching AI agents to run real engineering solvers, not toy demos

What it does

CAE Agent Hub is a collection of MCP servers, reusable agent skills, and browser-based result viewers aimed at engineering simulation. Instead of AI clients producing offline toy examples, they connect to your installed CAE applications and solvers — Abaqus/CAE, ANSYS Fluent and Workbench, AEDT/HFSS, Altair HyperWorks, LAMMPS, OVITO, CalculiX, Peridigm, and a FreeCAD → Elmer → ParaView pipeline — and run real jobs. The repo also ships a large set of Abaqus-specific skills covering everything from geometry and meshing to fatigue analysis and topology optimization.

The interesting bit

The architecture is a clean separation of concerns: MCP servers provide tool access to live solver sessions, Skills encode the modeling and validation workflow knowledge, and the solvers themselves do the actual math. Several workflows are explicitly “evidence-oriented” — they gate results on verification steps rather than trusting the agent’s word, which is a refreshingly skeptical stance for the agentic-simulation space.

Key highlights

• MCP servers for ten-plus CAE ecosystems, from commercial heavyweights (Abaqus, ANSYS, HyperWorks) to open-source tools (CalculiX, LAMMPS, Elmer)
• Deep Abaqus skill coverage: 20+ skills spanning geometry, materials, contact, dynamics, thermal, fatigue, and optimization workflows
• Browser-based viewer for inspecting lightweight result_mesh.json results without keeping the solver open
• CalculiX MCP includes two-stage sizing optimization and modal analysis with viewer-renderable mode shapes
• Bilingual (English/Chinese) documentation throughout

Caveats

• The Peridigm MCP and its fracture skill are marked as prototypes with only “verified profiles” — treat as experimental
• Some historical text-to-cae naming lingers for viewer compatibility, which hints at an ongoing rename
• You obviously need the underlying CAE applications and licenses installed; this repo is the glue, not the solvers

Verdict

Worth a look if you’re an engineer already using AI coding clients and want them to touch your real simulation stack. If you don’t have Abaqus or Fluent licenses sitting around, most of this will remain theoretical.
