Coming Soon

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

CalculiX Gmsh Python Anthropic Claude

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.

What We're Building

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.

How It Works

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.

01

Describe

Load your CAD file and describe materials, loads, constraints — in plain English.

02

Generate

AI creates Gmsh mesh scripts and CalculiX input files. Every file is visible and editable.

03

Solve

CalculiX runs locally on your machine. Your geometry never leaves your computer.

04

Validate

Automatic checks: reaction equilibrium, mesh convergence, hand-calc comparison.

05

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.
