Nodes - Hybrido Fluids (HyFLIP)

Hybrido is RealFlow's simulation engine for large scale fluids, for example ocean surfaces, rolling and breaking waves, and other scenes with huge amounts of water. When we talk about this technology we have to differentiate between two basic elements: 

• HyFLIP (Hybrido fluids)
• HySPH (Hybrido secondaries)

HyFLIP is used to simulate the so-called core fluid – the main body of water. The level of detail that can be achieved with HyFLIP fluids is very high and you can observe splash-like structures when waves are breaking or objects interact with the fluid. But in most cases, a Hybrido simulation requires far more more detail, because in nature you can observe other phenomena:

• small scale splashes

• foam

• bubbles

• mist and haze

These parts are simulated with RealFlow's → HySPH technology, and they are also called “secondary elements”.

Another thing you can see on wave surfaces are smaller waves and ripples. The waves often show sharp crests and a specific kind of motion. This wave structure can be added to the HyFLIP core fluid on demand to enhance realism. It is named → “ocean statistical spectrum” and in many cases you will also find the term “displacement”. Both terms describe exactly the same.

The diagram below shows the different elements of RealFlow's Hybrido technology:

We have prepared two tutorials where you will learn how to create a basic HyFLIP scene, add a displacement layer, and mesh the result:
