Engineering simulation,
guided by AI.
We're building an AI copilot for structural and thermal simulation. Describe what you want to analyze, review every step in text or in 3D, and validate results with confidence. Powered by battle-tested open-source solvers, running entirely on your machine.
Powered by validated open-source solvers
Great solvers, painful workflows
Engineering simulation should be accessible and frictionless. Today, it's neither.
Priced for enterprises, not engineers
Commercial FEA tools price out most engineers. Mid-market teams routinely spend six figures a year on licenses before running a single analysis.
Steep learning curve
Complex GUIs, proprietary scripting languages, and fragmented toolchains. 47% of mid-size firms lack the in-house expertise to even get started.
Slow, manual iteration
Adjust a load case or refine a mesh and you're back in menus, re-exporting, re-running. Most engineers run one analysis when they should run ten.
No audit trail
Simulation setups buried in project files with no clear record of assumptions made. Hard to verify, hard to share, hard to explain to a reviewer.
An AI copilot that shows its work
Simulyx guides you through every step of a simulation. You stay in control, the AI handles the complexity.
Conversational, with 3D context when it matters
Describe your analysis in plain English, no menu-diving, no manual file wiring. When spatial context helps, Simulyx opens a 3D view, then returns to the conversation. The learning curve flattens from months to minutes.
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. Know your results are trustworthy.
Battle-tested solvers
CalculiX and Gmsh are proven in aerospace and automotive programs worldwide. Peer-reviewed, validated against established benchmarks, with full solver source you can inspect.
Priced for engineers, not enterprises
Starting from $49/month, a fraction of commercial FEA tool costs. Free tier included. No procurement approval required.
Launching with structural and thermal FEA. The same copilot architecture extends to CFD, electromagnetics, and beyond.
Your copilot for the full simulation workflow
Describe your problem. Simulyx handles the tedious parts: meshing, solver setup, validation checks. Iterate freely through conversation, and focus on the engineering decisions that matter.
Describe
Load your CAD file and describe materials, loads, and constraints in plain English.
Set up
Simulyx handles meshing and solver configuration. Review geometry and boundary conditions in 3D at key checkpoints, then confirm before anything runs.
Solve and iterate
The solver runs locally, your data stays on your machine. Re-run with different loads, materials, or mesh densities through conversation.
Validate
Automatic checks: reaction equilibrium, mesh convergence, hand-calc comparison. Inspect deformation and stress fields visually.
Document
Engineering report drafted from real analysis data. Review and refine, not start from scratch.
Built for engineers who simulate
From solo consultants to mid-size product teams, Simulyx fits 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.
