TCAE

The Pythagoras cup (also known as the Greedy Cup or Tantalus cup) is a clever ancient drinking vessel that beautifully combines philosophy, ethics, and fluid mechanics.

It looks like an ordinary cup—but inside, it hides a siphon mechanism.
Fill it only up to the marked level, and everything works fine.
Get greedy and pour just a little too much, and the cup suddenly empties itself completely through a hole in the bottom.

No magic.
Just physics.
Fluid mechanics at its finest.

Traditionally attributed to Pythagoras, the cup carries a timeless message:

Exceed the limit, and you lose everything.

And yes—this is exactly what we simulated.
The CFD results look great. 🔥

👉 Good news for simulation enthusiasts:
The upcoming TCAE 26.03 will support Volume of Fluid (VOF) multiphase flows.

Soon on your computers.
