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 dynamicsA 2-meter whip solved in Ansys LS-DYNA as a chain of 800 articulated tapered links, cast back over the hand and thrown like the real thing: a 10 m/s arm stroke with a 160-degree wrist flick laid over it. The…
✦ AIsun kinkEvery heatwave produces the same photo: a dead-straight railroad track lying in a lazy S-curve, pushed there by nothing but sunshine -- the sun kink. Continuous welded rail is anchored so it cannot expand, so…
✦ AIelectromagneticsThe hot and cold spots inside a 2.45 GHz microwave-oven cavity, solved from Maxwell's equations in Ansys HFSS. A generic countertop cavity is solved empty and with a chocolate-bar load at six turntable angles;…
A place to experiment in public — AI-run studies, shared openly for discussion and learning, not as engineering advice.
