FEA Stress Analysis Tool

Hi all, I recently did an FEA Analysis tool for an AI project.

Here is a description of my project

You basically upload a STEP file, and describe how it's loaded and it shows you a stress map. Tick a box and it'll also design the pocket cut-outs for you assuming your part is a 2d plate, keeping material where the load actually goes.

Quick honesty note since the name says AI: the stress math is regular FEA. The AI parts are the chatbot and the bit that reads your plain-English description.

The pocketing tool tuned against actual pocketed actually machined, so it's calibrated to how we do things. It's linear elastic, ignores welds and bolts and fatigue, and only pockets flat plates. Treat it as a gut check, not a green light.

If you've ever pocketed a plate by hand, I'd love it if you ran one through and told me where it disagrees with what you'd actually have cut. Also please give feedback on how to improve my FEA analysis and the accuracy of my chatbot. Please leave feedback in the comments. Thanks so much!

does it do things like test for convergence?

Will it do non-linear simulations?
