Fluid Lab — Interactive Fluid, Smoke & Wave Simulations
Make a disturbance. Follow the flow.
Fluid Lab is a browser collection for exploring flowing dye, rising smoke, three-dimensional fluid volumes and waves. Stir a current, place an obstacle or build a wave experiment, then watch how the disturbance develops. Comparison and saved-scene tools make it easier to investigate a single change.

Try a small experiment.
- Start in Flow and introduce a small amount of dye. Let the current develop before adding another disturbance.
- Compare two settings with the same starting experiment. Change one variable and use the graphs to describe the difference.
- Try the 3D or Waves workspace. Use the available depth controls, sources or barriers to explore what that model adds.
A couple of useful questions.
Are waves and moving dye the same simulation?
They represent different things. A dye view follows a transported quantity in flow, while a wave model follows a disturbance of a surface or field. Fluid Lab groups these related experiences but explains their models separately.
Why compare two runs side by side?
A matched comparison helps separate the effect of a setting from differences in the starting state or elapsed time. One-variable experiments make the result easier to explain.
Know what the tool represents.
Fluid Lab contains several numerical and illustrative models, not one universal fluid solver. Use each workspace’s source and limit notes when interpreting viscosity, smoke, waves, obstacles or three-dimensional behavior.
