Simulations

A Swiss-cheese wedge warms on a passive dark platform, softens and slowly spreads into a golden puddle. The heater input (0 off, 1 full heat) directly controls heating and softening; the platform stays dark and supplies no heat; conservative downward and sideways fluxes retain all the cheese. The three holes close as the wedge collapses. Run about 100 steps to see the transformation, or recompile to restore the wedge. This is a stylized lattice melting model, not calibrated food physics; it omits latent heat, elasticity and surface tension.

One electron wave packet meets an ideal barrier with two slits. Cyan shows probability density; amber accumulates probability absorbed by the detector. Ordinary Hyle evolves a 192 × 160 Schrödinger lattice with norm-preserving pair rotations. Run roughly 800 ticks to collect the transmitted packet; Step and the timeline reveal diffraction and interference. CPU-64 is the reference; GPU-32 supports this program. This is a 2D nonrelativistic model with ideal walls and approximate absorbing boundaries. The detector shows expected probabilities, not individual random electron hits. Recompile restores the normalized incident packet. See Hyle docs: Learn / Quantum double slit.

A suspended ball of water falls into a dry glass tank, hits the floor and spreads. D3Q19 free-surface lattice Boltzmann dynamics carry momentum and conserve liquid mass. Blue opacity shows cell fill; brighter water is moving faster. Use a cutaway to see the impact, or recompile to restore the ball. This is a coarse lattice experiment without surface tension or simulated air, not a realistic droplet or splash model.

A full 16 × 16 × 16 acoustic volume. Opposite pulses start at different heights and travel through a double-aperture reflector; the outer layer absorbs energy. In Studio, open View options and choose Single layer or Cutaway on X, Y or Z to reveal the interior. Paint Crest or Trough into empty cells to add a pulse, or recompile to restore the initial scene. This is a stylized scalar wave model, not a fluid solver.

Five copper vents emit translucent blue plumes above an obsidian platform. Mist rises by creating weaker cells above itself, then dissipates. The vents continuously refill gaps for a repeating fountain.

Three impulses spread and interfere across a luminous lattice. Neighbor differences accelerate each cell and a second phase integrates displacement. Color shows signed displacement; this is a discrete wave experiment.

Two colors of grains fall onto a stepped basalt basin. Downward mass transport and empty-cell cleanup form a simple settling experiment. Paint GoldSand or RoseSand above the basin to keep the cascade going. Gold and rose colors identify the two grain models throughout their fall.

A spreading fire crosses a planted island, leaving charcoal behind. Nearby heat ignites trees; each burning cell consumes its fuel. Recompile to restore the forest, or paint Fire to start another front.

A garden of cyan and rose crystals climbs upward and branches into smaller spires. Energy limits each branch: paint a fresh crystal to grow another cluster. This is a stylized growth model, not a chemistry solver.
