"Design me a 3d printable rocket engine for a hobby rocket project. Verify it's design in a full simulation. Iterate until it works reliably in simulation based on a verified printable design on a consumer laser sintering device (or substitute contract manufacture for under 1000 dollars)."

This is a hobby version of a project, but you can imagine commercial versions of the same prompt for new databases, genomics studies, material analysis, operating systems etc.

From the prompt it seems evident the envisioned user doesn't have an interest in designing the motor themselves, so why not simply buy a stock motor?

I’m not convinced at all that the model won’t just get stuck in a loop where it doesn’t understand how to fix the broken rocket. I see similar failure modes in far simpler projects strictly confined to coding. This feels closer to “make me a profitable business, make no mistakes” than to a simple coding project.

Are there already skills around modelling, simulation and post-processing? Any pointers?

Stop it, you tease. I'm getting a little tingly
