Professional FEA,
guided by AI.
We're building an AI copilot for structural analysis. Describe what you want to analyze, review every step the AI takes, and validate results with confidence — using real open-source solvers running locally on your machine.

Built on validated open-source solvers
Engineering simulation is broken
Professional FEA tools cost a fortune, take months to master, hide their work, and produce results you can't easily explain or document.
$20K–60K/year licenses
Commercial FEA tools price out 90% of engineers. Even mid-market teams face $135K–$700K in annual license costs.
Black-box results
Pretty stress plots with no convergence evidence, no reaction checks, no way to verify boundary conditions or mesh quality.
Months to become productive
Complex GUIs with hundreds of menus, proprietary scripting, and 47% of firms lack in-house FEA expertise to onboard effectively.
An AI that shows its work
Simulyx will guide you through every step of a structural analysis — you stay in control, the AI handles the complexity.
Natural language interface
Describe your analysis in plain English. Simulyx will understand engineering intent — materials, loads, constraints, and what results matter.
Full transparency
Every generated file, solver command, and validation check will be visible and editable. The AI is a copilot — you make the engineering decisions.
Your geometry stays local
All solvers will run on your machine. Your STEP files, mesh data, and results never leave your computer. Optional fully-local mode with Ollama.
Built-in validation
Automatic reaction equilibrium checks, mesh convergence studies, and hand-calculation comparisons — so you know your results are trustworthy.
Real physics, not approximations
CalculiX and Gmsh — battle-tested solvers used by aerospace and automotive engineers. Actual governing equations, not neural network predictions.
Priced for engineers, not enterprises
Starting from $49/month — a fraction of commercial FEA tool costs. Free tier included. No procurement approval required.
From description to validated results
Describe your analysis in natural language. Simulyx will guide you through every step — you stay in control, the AI handles the complexity.
Describe
Load your CAD file and describe materials, loads, constraints — in plain English.
Generate
AI creates Gmsh mesh scripts and CalculiX input files. Every file is visible and editable.
Solve
CalculiX runs locally on your machine. Your geometry never leaves your computer.
Validate
Automatic checks: reaction equilibrium, mesh convergence, hand-calc comparison.
Document
Engineering report drafted from real analysis data. Review and refine — not start from scratch.
Built for engineers who simulate
Whether you're a solo consultant or part of a team, Simulyx will fit your workflow.
Individual engineers & freelancers
Professional simulation without enterprise budgets. Validate a design and deliver results without waiting on specialist availability.
Small engineering teams
Let more team members run standard analyses confidently — freeing the specialist for complex problems and design decisions.
IP-sensitive organizations
Defense, medical device, and proprietary design work. Local-first architecture means your geometry never touches a cloud server.
