Play with it
Both demos run on your device. Change the Reynolds number, watch how the flow responds, and explore the solver code shown below each simulation.
Lid-driven cavityA box with a moving lid. Watch the corner eddies and shear layers appear as Re climbs.

Flow over a squareA wake that is steady, then sheds, then turns messy, up to Re = 10,000.

A first week, if you get hooked
- Run the cavity at different Reynolds numbers. What changes in the main vortex and the corner eddies?
- Read the solver on the page. Find the collision and streaming steps.
- Change one thing: the obstacle size, the lid speed, the collision step.
- Tell us what you saw. That is a thesis conversation.
