Dev shares prompt trick for rapidly iterating a physics sim engine one concept at a time
doodlestein · x · 2026-11-01
Developer doodlestein (Dicklesworthstone) shares how he's improving FrankenSim, his physics simulation project, at a rapid clip: his prompts end with "Focus on realistic treatment of <INSERTPHYSICSTERM> throughout all applications", swapping in a single term (convection, radiation, contact mechanics, real gas, etc.) from a list each iteration. The precondition is an architecture where every module has a logical place and a means of combining with others, so nothing devolves into chaos. Commit logs show a steady stream of focused feat/fix commits every few minutes across thermal, airflow, solid, render and coupling modules — a reusable "architecture in place + one-concept-per-prompt" cadence for AI-driven development.
