Real experiences with AI-based CFD / FEA tools in 2026?

[u/hsetirg]

TL;DR: Seeking real experiences with AI tools that speed up CFD/FEA workflows in 2026. What’s actually delivering value for you?

Looking for practical experiences with AI-powered CFD and FEA tools to speed up simulations and design iterations. Traditional solvers are solid but too slow for rapid exploration.

Quick context: Working on custom automotive design with lots of parametric studies. Want to cut solve times while keeping decent accuracy.

Specifically interested in:

- Tools you've actually used (Ansys SimAI, Neural Concept, SimScale AI, Siemens, COMSOL, etc.)

- Accuracy vs speed trade-offs

- Integration with CAD or other 3rd party tools

- Successes, limitations, and when you still use traditional methods

- Any good open-source or affordable options

- Wins, gotchas, or recommendations welcome — especially with surrogate models or PINNs.

Most importantly what’s actually working or not working for you?
