Every study here was built, run, and written by the AI pipeline on real Ansys tools.
✦ AIstructural dynamicsA community member asked the classic playground question at engineering scale: pack a pedestrian bridge with people and compare everyone standing still, everyone jumping randomly, and everyone jumping in…
✦ AIrigid-body dynamicsEveryone has leaned back in an office chair and felt that half-second of panic. It turns out how far you can go has almost nothing to do with how hard you lean -- it's set by the five-star base. A chair tips…
✦ AIice throwWinter wind farms post 'beware of falling ice' signs, and the industry's classic siting rule says stay back 1.5 x (rotor diameter + hub height) - a 360 m circle for a modern 3.4 MW machine. We tested the rule…
✦ AIrigid-body dynamicsThat one player who swears their dice are cursed -- is there anything to it? We tested it in Ansys LS-DYNA with a rigid-body Monte-Carlo: pour 1,024 dice at once (random orientation + spin) onto a frictional…
✦ AIadditive manufacturingGE printed a jet-engine fuel nozzle as a single grown-from-powder block - but two prints from the same machine and powder can come out one flight-ready and one full of pores, decided in a pool of molten…
✦ AISTOP analysisCompare mirror materials at the same temperature gradient and aluminum is 474 times worse than Zerodur. Compare them at the same absorbed heat and it beats fused silica. Same solver, different question. PLUS a…
✦ AIexternal aerodynamicsFive Ansys Fluent solves of one generic tractor-trailer -- bare, then with a roof deflector, trailer side skirts and a boat tail fitted individually, then all three together. The roof deflector alone takes the…
✦ AIgranular mechanicsFlat, lentil-shaped candy-coated chocolates look like they nestle together better than round gumballs -- and a famous 2004 Princeton result (Donev et al., Science) found that oblate shapes really do pack…
✦ AIGranular Flow / DEM · Ansys RockyAn hourglass runs down at a steady, even rate from the first grain to the last, no matter how full the top bulb is — which is the whole reason it can measure time. A draining bottle of water can’t: it gushes…
✦ AIelectronics coolingThe couch-gaming argument, settled the way an electronics-cooling engineer would: one 15.6" gaming laptop, one 135 W CPU+GPU load, four surfaces (hard desk, lap, a thick duvet with the intake vents…
✦ AIelectromagneticsDrop a strong magnet down a copper pipe and it drifts down like it's falling through honey -- even though copper isn't magnetic. We built the magnet's field in Ansys Maxwell (2D axisymmetric magnetostatic,…
✦ AIcomputational fluid dynamicsThree reservoir heads over one ogee crest, spanning a 4.9-fold change in discharge. Fluent reproduces the USACE/WES rating curve to within 5 % at every one of them. What the 1D method cannot give at all is…
✦ AIintegrated photonicsA community question - can light get stuck in a traffic jam? - answered with Ansys Lumerical FDTD by building waveguide intersections where 4, 8, 12 and 16 silicon guides meet at a single point. The answer has…
✦ AIaerodynamicsThe classic urban legend, settled with CFD and explicit dynamics. Ansys Fluent puts the drag coefficient of a face-on penny at 1.17 — right on the textbook flat-disc value — which caps its terminal velocity…
✦ AIElectronics Reliability · Ansys SherlockBoards fail when solder joints fatigue, not when chips die. We pointed Sherlock's physics-of-failure engine at an open-source Arduino Uno R3 under a MIL-STD-810H thermal/vibration life — built entirely from…
✦ AIlens designLook through a cheap magnifier at something bright and you see a colored fringe - blue on one edge, red on the other. That is chromatic aberration: a single lens can't focus all colors to the same point…
✦ AIFluids · Ansys FluentThin-airfoil theory says the lift-curve slope should be 2π per radian. We swept the angle of attack on a NACA 0012 in inviscid CFD and landed at 0.96×2π — textbook, with the finite-domain effect…
✦ AIMarine CFD / Cavitation · Ansys FluentSpin a propeller fast enough and the water on the low-pressure side of the blade boils — not from heat, but because the pressure drops below water’s vapor pressure at room temperature. Those vapor pockets…
✦ AIDynamics · Ansys LS-DYNAA 52 mm domino, flicked with a fingertip, knocks over a slightly bigger one — thirteen times in a row — until a 464 mm slab the size of a paving stone goes over (~9× the size, thousands of times the…
✦ AIimpactWe built a tempered side window in Ansys LS-DYNA, arrested the door frame the way a latch does, and turned the slam up until it broke. A normal-to-hard slam (door-edge ~1-3 m/s) loads the glass to only 40-90…
✦ AIanalog computingBefore silicon, engineers computed with physical analog machines -- soap films that found minimal surfaces, resistor grids that solved for voltages, water tanks that integrated equations -- that didn't…
✦ AIaerothermodynamicsA scripted Ansys Fluent sweep resolves the bow shock over a re-entry body across a Mach 6 envelope: the shock detaches on the blunt nose and stands off by the Billig amount, forming the shock-heated cushion…
✦ AIOptical / AOI · Ansys SpeosThe same scratch on brushed aluminum can be glaring or invisible depending only on where the light comes from. We simulated three machine-vision lighting schemes — bright-field, dark-field, diffuse dome —…
✦ AIScripting & Automation · Ansys MechanicalThe engineering world’s favorite dare is ‘but does it run DOOM?’ — so we made it run on the one tool we live in all day. The real 1993 DOOM engine boots inside Ansys Mechanical, with every frame painted onto…
✦ AIgranular flowA sand pendulum engraves its rose with two pieces of physics: a Blackburn suspension's two detuned frequencies make the swing ellipse precess into a rosette (86 petals; measured 26.9 vs predicted 26 per…
✦ AIStructures · Ansys MechanicalThe Navy sets off 40,000-pound charges next to its carriers to prove they survive an underwater shock. For everything else there's DDAM — the public NAVSEA method. We ran the full thing on an equipment…
✦ AIElectronics Reliability · Ansys SherlockWe aimed the same Sherlock physics-of-failure engine we once pointed at a military board at GM's under-hood spec, GMW3172. Under code-H (−40/+125 °C) the solder joints start failing in under a year — and the…
✦ AImetalensA flat 2 mm metalens for the thermal band -- 349,113 silicon pillars 11.5 um thick, each one an entry from a 33-atom library measured a solve at a time in Ansys Lumerical FDTD. At its 10 um design wavelength…
✦ AIexternal aerodynamicsA dimpled golf ball at 119 mph has a drag coefficient near 0.25; a smooth ball the same size at the same speed sits near 0.47. The dimples do that by tripping the boundary layer turbulent so it stays attached…
✦ AIillumination opticsCurved glass skyscrapers occasionally make the news for scorching the sidewalk or warping a parked car's plastic trim. Glass isn't a lens and reflects only ~10% of the sun that hits it, so how does a building…
✦ AIImpact / Fracture · Ansys LS-DYNADrop a glass bauble and it either bounces or bursts — and what it lands on matters as much as how far it fell. We ran an explicit drop test across 13 heights and 3 surfaces, then turned the peak tensile stress…
✦ AIImpact / Crush · Ansys LS-DYNACrushing an empty can is the same thin-wall buckling that lets a car’s crumple zone soak up a crash — at 0.15 mm scale. We crushed a 16-oz aluminum can in an explicit Ansys LS-DYNA solve: real shell elements,…
✦ AIpower electronicsA scripted Ansys Q3D sweep of 27 cases shows a copper busbar's AC resistance climbing to ~8.5x its DC value by 50 kHz from skin effect; flattening the section at fixed copper cuts the penalty ~1.4x but edge…
✦ AIphotonicsA visible-light TiO2 metalens -- 8,724,901 pillars on a 1.1 um stack (~64x thinner than a hair), f/2 at 550 nm -- built from an Ansys Lumerical FDTD atom library and propagated to image. It focuses green to a…
✦ AIphotonicsCrush a brilliant-blue Morpho butterfly wing and the blue vanishes - the powder left over is brown, because there is no blue pigment anywhere in it. The color is structural: a stack of transparent nanoscale…
✦ AIturbulent mixingWhen hot and cold water meet in a piping tee, they do not blend on contact - the hot branch fires in as a turbulent jet and the two streams stay a sharp, churning interface for a surprising distance…
✦ AIexplicit dynamicsSizing a composite part comes down to one question: what load do you design against? For a carbon quadcopter arm the honest answer is 'whatever a crash does to it' - so instead of assuming a hard-landing load,…
✦ AIrigid-body dynamicsNot clumsiness, not bad luck — geometry. We built the tumble in Ansys LS-DYNA: a bread slab is nudged off a table edge, pivots, detaches, and free-falls onto the floor while it spins. Off a normal 0.75 m table…
✦ AIMembranes / Explicit Dynamics · Ansys LS-DYNAA balloon is a pressure vessel you can buy for a nickel — a thin rubber membrane holding back internal pressure with pure tension, the same job done by a car airbag, a tire, an angioplasty balloon in an…
✦ AIparasitic extractionA charging cable looks like a dumb piece of copper, but electrically it is a real component whose parasitic resistance, inductance, and capacitance decide how much power turns into heat, how hard fast edges…
✦ AIStructures · LS-DYNACan a singer really shatter a wine glass? We drove a glass at its ovalling resonance in an explicit fracture simulation until it cracked — and proved it's the resonance, not the volume, with an off-note…
✦ AIexplicit dynamicsAn optiSLang-driven search crushed 36 crush-tube designs in Ansys LS-DYNA to map the trade-off between energy absorbed and peak crush force: wall thickness sets the peak, a trigger bead trades that peak for…
✦ AIexplicit dynamicsThe old myth: if the cable snaps and the elevator plummets, jump straight up right before it hits and you'll be fine. We put it to an Ansys LS-DYNA explicit-impact test. A simplified but honest occupant -- a…
✦ AIpropulsionA scripted Ansys Fluent study solves a solid-rocket motor's port+nozzle flow across the burn (Pc ~1.3-8.5 MPa, thrust ~790-5930 N, matching internal ballistics to ~1.1%), then maps four grain families onto the…
✦ AIvehicle aerodynamicsThe bar-stool argument settled in a virtual wind tunnel: a generic pickup at 70 mph (31.3 m/s), solved in Ansys Fluent as steady RANS (k-omega SST) with the tailgate up versus dropped, everything else…
✦ AIturbomachineryWe ran the standard Ansys turbomachinery design chain end to end, headless, with no GUI at any step: define a blade from parameters in BladeGen, mesh a single passage in TurboGrid, and solve it in CFX as a…
✦ AInon-Newtonian flowThe viral cornstarch-pool stunt, answered honestly — now in two rounds. Round 1: the real reason you can run on oobleck is a dynamic jamming front (Waitukaitis & Jaeger 2012), not a steady viscosity, so the…
✦ AInon-sequential ray tracingSpencer asked whether we could predict the colors of a wildfire sky from the amount of smoke in the air - the blue-to-milky-white-to-blood-red sequence everyone remembers from a bad fire season. So we built…
✦ AIStructures · Ansys Mechanical (2D plane stress)Put a toddler on your shoulders and you already know where it ends up — your lower back. We asked the physics why. A stick-figure dad becomes a 2D plane-stress FE model, and the same 13 kg kid is run two ways:…
✦ AIStructures · Ansys MechanicalThe dangerous stresses in real machinery live at the interfaces — the pin bore, the rod small-end, the bolted joint — exactly where a single-part model can't see them. We put a nine-part slider-crank through a…
✦ AIImpact / SPH · Ansys LS-DYNAA full sippy cup leaves a small hand, tumbles to the floor, and the lid gives up at exactly the wrong moment. For Father’s Day we put that tiny catastrophe into LS-DYNA: the milk is thousands of SPH fluid…
✦ AIcontact mechanicsTwo 7 kg steel spheres, one struck into one at rest — a bowling-ball Newton's cradle, run in two solvers. Ansys Mechanical (implicit) reproduced the contact stress to within 8% of Hertz theory but held the…
✦ AIelectronics coolingA phone has no fan: every watt from its processor leaves only by slow natural convection and infrared radiation off its outer surfaces. We built a simplified smartphone (aluminum back, Li-ion battery, FR-4…
✦ AIGranular · Ansys Rocky DEMDrop 500 beads through a triangle of pegs and a bell curve assembles itself in the bins below — the Central Limit Theorem you can watch. We built the Price-Is-Right Plinko board in Rocky DEM; the Gaussian…
✦ AIImpact · Ansys LS-DYNAHigh-speed footage shows the backwards-feeling truth: the bullet, not the plate, is what comes apart. We rebuilt a lead-core round splattering on hardened armor at 850 m/s in LS-DYNA — ~90% of the impact…
✦ AIOptics / Dispersion · Ansys SpeosHold a diamond under a lamp and it throws little darts of pure color — jewelers call it fire, and it is not the white sparkle of brilliance but the stone splitting white light into a spectrum, exactly like a…
✦ AIbuoyant plumeFire up a grill and someone two yards over smells it within a minute -- the smoke seems to vanish upward, yet the smell crosses the fence. We simulated a backyard grill in Ansys Fluent as a TRANSIENT buoyant…
✦ AIelectromagneticsA scripted Ansys HFSS sweep moves one blade antenna across 5 mount positions on a UAS fuselage; ground-station coverage swings from 75.0% to 92.7% of the lower sky (best: belly-mid) with the same antenna --…
✦ AIrocket nozzleDrop the outside pressure by a factor of a thousand and a choked engine's flow does not change at all. Thrust still climbs 45 percent — through the pressure term, not the flow. PLUS a Part 2: a scripted Fluent…
✦ AIGeometry / CAD prep · Ansys GeometryCAD never arrives mesh-ready — so how much of the prep can you script, headless, with PyAnsys Geometry? We built three deliberately messy parts and ran it live, pros and limits straight. The pros: defeaturing,…
✦ AIGranular flow · Ansys Rocky DEMMixing is the rare process that only runs one way — and industry depends on it for every tablet and every batch. We built a small auger blender and let Ansys Rocky’s GPU discrete-element physics fold two…
✦ AIantennasThe antenna in a Wi-Fi router, a Bluetooth case, or a GPS puck is usually a flat rectangle of copper on a circuit board — a microstrip patch. We designed one for 2.4 GHz in Ansys HFSS, fed it with an inset…
✦ AIdiffractive opticsA diffraction grating sends every color off at its own angle, and tilting the incoming beam swings the whole fan - up to a hard limit. The grating equation sin(theta_m) = sin(theta_i) + m*lambda/d has an…
✦ AIelectromagneticsA scripted Ansys Maxwell + Mechanical study of a copper solenoid shows the magnetic pressure (B^2/2mu0) climbing as the square of the field to ~159 MPa at 20 T -- enough to yield bare copper by ~9.7 T. Field…
✦ AIImpact · Ansys LS-DYNASeal a ping-pong ball in a long tube, pump out the air, and break the seal — the atmosphere drives that 2.7 gram ball out the muzzle at roughly the speed of sound, fast enough to blast a clean hole through a…
✦ AIStructures · Ansys MechanicalA raw FE stress at a weld means nothing against a code allowable. We ran the full ASME Section VIII-2 Part 5 design-by-analysis on a nozzle junction — linearizing the stress on classification lines, sorting it…
✦ AIimpactA Prince Rupert's drop laughs off a hydraulic press on its bulbous head but detonates from a finger-flick on its wispy tail. Round 1 built it in Ansys LS-DYNA with a two-layer effective strength and ran both…
✦ AIImpact / Explicit Dynamics · Ansys LS-DYNAThe internet runs on destruction — bullets fired through stacks of steel, a hydraulic press flattening a soda can, a bowling ball dropped onto a trampoline, a heavy weight cratering a panel — and every one of…
✦ AIweldingA single-pass butt weld on 6 mm mild steel, modeled end to end in Ansys LS-DYNA as a coupled thermal-mechanical transient: a Goldak double-ellipsoid heat source traveling a real node path at 5 mm/s, a bead of…
✦ AIlow-frequency electromagneticsAn induction cooktop drives an alternating magnetic field from a coil under the glass into the pan, where it induces eddy currents that heat the metal from the inside. We built the coil-and-pan system in Ansys…
✦ AIhypervelocity impactA chip of aluminum the size of a pea moving at 7 km/s carries roughly the kinetic energy of a hand grenade, and low Earth orbit holds over a million objects in the 1-10 cm band that is big enough to kill a…
✦ AIexplicit dynamicsAn anonymous community member asked a small, secretly-deep question: how fast does a minifigure fall, and does it survive the landing? We gave the test subject a name - Chip, our minifigure-style crash-test…
✦ AIthermalA car holding 100 km/h down a 12% grade pours ~23.4 kW into each front disc. Three hand estimates of the band temperature span nearly 1000 C and two predict melting; a coupled Ansys Mechanical…
✦ AIBlast / FSI · Ansys LS-DYNAAn enclosure's job isn't to contain an internal blast — it's to direct it. We detonated a 25 g TNT-equivalent charge inside a sealed steel room with an X-shaped relief panel on the back, using a multi-material…
✦ AIFluids / Fluidic Diodes · Ansys FluentTesla patented a pipe that lets fluid run one way easier than the other — no flaps, no springs, no moving parts — and the internet keeps claiming it blocks reverse flow 200× harder. That number is nonsense, so…
✦ AIsoft materialsThe slow-motion internet classic, put to an explicit-dynamics solve twice over. Ansys LS-DYNA squeezes a layered melon (soft water-filled flesh under a stiffer rind) with an equatorial belt pressure that…
✦ AIurban windA 50 mph wind driven through two 120 m towers in Ansys Fluent (k-omega SST, 1.8M-cell prism mesh, empty-domain amplification reference) shows the street gap is a sheltered pocket running about a third slower…
✦ AIgranular mechanicsThe cartoon fantasy of diving into a vault of gold is impossible -- and not because gold is hard. We poured a bed of 526 solid-gold coins (each a real coin, 28 mm across and 3.5 mm thick) into a bin in Ansys…
✦ AIice mechanicsCommunity member IceRoadTruckers asked the northern-winter question with real stakes: how thick does lake ice have to be before it holds a truck? The old field rule is 'twelve inches for a medium truck' - so…
✦ AIrandom vibrationBolt an enduro headlight rigid and its first mode is 239 Hz. On two three-gram rubber bushings it is 13.6 Hz - and every number that matters belongs to the rubber.
✦ AIcavitationThe famous snap is said to boil water. It doesn't - it cavitates. Ansys Fluent puts a 2D-axisymmetric model of the claw's sharp-orifice jet at a grid-converged inception cavitation number of sigma_i ~ 0.44,…
✦ AIcomputational fluid dynamicsEffectiveness-NTU sizes a heat-recovery core in one line and assumes every supply channel gets the same air. Solving the header and all 64 supply channels together, a side-entry plenum delivers a 25 % spread…
✦ AIadditive manufacturingA foundry patternmaker's shrink rule is deliberately oversized so the casting cools to the right size. Metal 3D printing needs the same idea, spatially varying: a laser-fused part locks in shrinkage layer by…
✦ AIsilicon photonicsA fiber-to-chip inverse-taper edge coupler solved in Ansys Lumerical 3D FDTD (220 nm SOI, 2.5 um lensed-fiber spot, 1550 nm): the best taper tip (180 nm) couples -1.14 dB but holds 1 dB only within +/-0.57 um…
✦ AIantennasAn anonymous community member asked the disaster-movie question: after a major earthquake knocks out conventional communications, could you clip a wire to a surviving office building and put a city back on the…
✦ AImodal analysisEvery solid object rings at natural frequencies fixed by its geometry, stiffness, and density -- so its sound is knowable from the CAD file before the part is ever cut. We asked Ansys what two shapes with…
✦ AIchain reactionLoad a box of mousetraps, balance two ping-pong balls on each, and drop in one more ball: the first ball snaps a trap, the trap flings its two balls into the air, they snap more traps, and the whole box erupts…
✦ AIAeroelastic FSI · Ansys FluentThe most-watched film in engineering history taught the wrong lesson for eighty years: the Tacoma Narrows deck didn’t fail from resonance — it failed from self-excited aeroelastic flutter. We set up the CFD…
✦ AISeakeeping / Multiphysics“A boat in water” is really several different simulations, depending on the question. We put the same boat through four Ansys solvers spanning three kinds of physics — AQWA’s frequency-domain potential flow (a…
✦ AIVOFSteve Mold's viral 'can water solve a maze?' demo, rebuilt on his EXACT 20x20 maze (extracted wall-for-wall from his video) in Ansys. Two senses of 'solve': (1) gravity-driven free-surface WATER, modeled as a…
✦ AIModal · Ansys MechanicalEvery wine glass has a pitch. A modal analysis finds the bowl's 'ping' — the ovalling mode at 813 Hz, about a G#5 — the exact note a voice would have to hit, and whether a human can deliver the energy.
✦ AIelectromagneticsA 20 kW servo motor solved in Ansys Maxwell and Mechanical. The textbook one-line iron-loss estimate looks 8x too high, but almost all of that is the assumed flux density, not the uniform-field assumption…
✦ AIelectronics coolingA scripted Ansys Icepak sweep of 23 board arrangements in a sealed fanless enclosure shows the hottest board swings 34 C (115->149 C) from rearrangement alone: in natural convection a high-power board buried…
✦ AImultiphaseThe candy's surface, not the soda, sets the height. A 0D degassing model turns Mentos nucleation-site density into a neck-exit froth velocity (4.1 / 8.1 / 12.2 m/s across a plausible release-fraction sweep);…
✦ AIFluids / Wind Loading · Ansys FluentA 620-pound cedar playset is a kite with a clubhouse — and the manufacturer anchors it with seven unrated corkscrew stakes. We put the actual structure in a digital wind tunnel: the retailer’s AR marketing…
✦ AIthermalPlunge a 850 C steel forging into oil and the skin cools in seconds while the thick core stays hot for minutes (Biot ~3.0). A coupled Ansys Mechanical solve -- transient thermal, then an elastoplastic…
✦ AIImpact / Inflatables · Ansys LS-DYNAThe internet’s favorite “will it pop?” challenge — a big inflatable in a parking lot, an escalating set of props thrown at it — rebuilt as an explicit Ansys LS-DYNA solve. The easy part is the props (rigid…
✦ AIcomputational fluid dynamicsThe ideal continuously-stirred tank has no term for where the influent pipe enters. Three inlet depths, solved as a tracer pulse in Fluent, put 44 to 76 % of the slug out of the tank within a fifth of a…
✦ AIwood dryingFresh-sawn green lumber has to be dried to be usable, but drying it too aggressively splits it along the grain (checking) and moves it (warping). A generic softwood 2x6 was dried in Ansys Mechanical to map…
✦ AIorbital thermalCommunity member Ryan Finelli asked about radiation-shielded housings for vacuum-rated electronics in a space environment - so we put the question to Ansys Mechanical with a twist worth knowing: the armor you…
✦ AIGranular · Ansys Rocky DEMShake a can of mixed nuts and the big Brazil nut climbs to the top — against gravity, against intuition. We buried a 20 mm nut at the bottom of a vibrated bed of 5 mm grains in Rocky DEM and watched it ratchet…
✦ AIacousticsA Rubens tube makes a sound wave visible: a propane-filled pipe with a row of flames along the top, a speaker at one end, and at the right note the flames freeze into a standing wave - tall at the pressure…
✦ AIStructures · Ansys MechanicalThose big square loops on a refinery pipe rack aren't a mistake — they're slack, engineered in so a hot line can grow without tearing its anchors apart. We ran the textbook ASME B31.3 case: a hot L-bend the…
✦ AIStructures · Ansys MechanicalHow fine is fine enough? A coarse mesh silently under-predicts a stress concentration. We meshed a holed tension coupon with linear elements and ran it from coarse to fine — the peak climbs out of a badly…
✦ AIDynamics · LS-DYNADrop a hanging slinky and the bottom just… waits. We reproduced the famous Veritasium demo in an explicit solver — the bottom moves 7× less than free-fall while the center of mass falls normally.
✦ AIStructural Stability / Buckling · Ansys MechanicalStep on an empty soda can and it never crumples the same way twice — sometimes a ring of folds, sometimes a spiral of diamonds. That isn’t randomness; it’s the most treacherous phenomenon in structural…

✦ AIModal · Ansys MechanicalThe note lives in one special mode — the symmetric one, where the tines cancel their forces at the stem so a holding hand can't damp it. We found it at 439 Hz: concert A. The FEA explains the whole design.
✦ AIFluids / VIV · Ansys FluentBehind every flagpole and bridge piling, the wake peels into an alternating vortex street that pushes sideways at a precise frequency — and shakes structures apart when it finds a resonance. We reproduced it…
✦ AIDrop Test / Explicit Dynamics · Ansys LS-DYNAEveryone has run the schoolyard egg-drop competition, where the score is binary: it cracked, or it didn’t. But a packaging engineer can’t ship “it didn’t crack” — they ship a number, the peak deceleration in…
✦ AIpower integrityA modern chip can swing its current draw by tens of amps in nanoseconds, and when it does the power rail sags — sag too far and the chip glitches or throttles, a brownout on a circuit board. We built a small…
✦ AIFluids · Ansys FluentRoberto Carlos's impossible free-kick, a baseball curveball, a topspin dip — all the same physics. We spun a cylinder in a 2D CFD flow and matched the published benchmark for sideways lift vs spin.
