Rand SIM Labs · Beta
The experimental wing of Rand Simulation — a public pipeline that turns community curiosity into real engineering simulations, no gatekeeping, just votes and Ansys.
Drop a simulation idea on the board — viral physics, myths, "what happens if…" Public ideas only.
Submit Your Idea →Upvote what you want to see simulated. Five votes sends it straight into the AI queue.
Cast Your Vote →The pipeline builds geometry, meshes it, solves in real Ansys tools, and writes the report.
See the Queue →Finished runs post to the blog — solve stats, mesh size, and honest caveats included.
Review the Blog →Real solves of the internet's favorite physics — every post names its own modeling shortcuts.
✦ AIexplicit dynamicsThe protection sequel to our hailstorm-vs-car study: the same generic steel hood and ice hailstones, now under four covers - bare, a cotton sheet, a thin foam pad, and an inflatable air enclosure the whole…
✦ AIice cubePour a warm drink on a freezer-cold ice cube and it splits with an audible crack. That is thermal shock, and a reader asked us to show exactly where and when the crack criterion is exceeded. We built a 25 mm…
✦ AIyield-stress fluidsThe upturned glass ketchup bottle, solved in Ansys Fluent as a two-phase VOF transient with published Herschel-Bulkley yield-stress rheology validated against an exact Buckingham-Reiner tube-flow solution to…
A place to experiment in public — AI-run studies, shared openly for discussion and learning, not as engineering advice.
