It's true that ideal liquids don't compress. It's also true that real-world liquids tend to contain dissolved gases, which of course do compress. It is further true that the ideal fluid models don't take quantum mechanics into account, which introduces small amounts of error per particle that accumulate in macrocosm.
liquids can compress, only slightly though, but it also dosnt tell what liquid it is supposed to act like so it can have as many properties as it wants as long as it stays within reason to a liquid
yes, there is that part about speed vs accuracy, and also liquids do compress and virtually all materials compress to some extent. physics teachers often have the tendency to call something "something" when it's only nearly "something". for example, when saying liquids are incompressible, they only mean liquids are nearly compressible. when liquids such as water are simulated as an incompressible fluid it's actually an idealization/simplification.

Nice work getting it not to crash with 10 substeps!
If i go lower than 20 it crashes like hell.. xD

I kinda thought your tensile stuff was more water-like... does it use up more processing power?

We need to add Solenthaler's Lagrangian pressure correction from SIGGRAPH 09

It's not specified what liquid it is, so it could be anything

Have you ever studied physics? Liquid arn't supposed to compress. Only gases can do that.

In theory liquids do not compress.

It's probably a trade off for speed vs accuracy. Simulations always screw up at the extreme end of things, such as massive speed or pressure.
Notice that oe-cake also has exploding water.

@kotsoft even water compresses you just have to know that though it seems it doesn't compress at all.

Have you ever studied programming?, it´s much easier to the system to simulate compressible water...
