A wind tunnel.

Place a shape. Follow the flow.
Explore a live, three-dimensional fluid field.

SIMULATION LIVE

Inlet velocity 1.0Viscosity 0.02Grid units, qualitative flow. Not calibrated SI values.Grid qualitySwitching reloads the page and resets shapes. Use Standard if the frame rate is low.

FLUID LOOKVorticity color contrastRed/blue: sign of the largest XYZ curl component. Color strength: curl magnitude. A visual aid, not one universal clockwise direction in 3D.Visual swirl retentionAdvected dye released at the start of the grid. Swirl retention uses vorticity confinement: an artistic force, not validated shedding. Set to zero for the original velocity solver.

ADD AN OBJECT

Or tap an object in the view to select it, then drag it. Shift-drag (or the Drag button) moves it up and down. Arrow keys nudge, Delete removes.SELECTED OBJECTX · ALONG TUNNEL

Type exact values or use the sliders. Local XYZ Euler angles, degrees. Releasing a drag or changing a value resets the flow and updates the solid mask. Snap dragging to whole units

IMPORT STL / OBJClosed meshes, max 10 MB / 60,000 triangles. Import fits the longest axis to the size control.Drag proxy: startingQualitative selected-shape pressure + viscous proxy. Not Newtons or a validated force.
