Although the Hybrido solvers in previous RealFlow version have already been based on cutting-edge technology, we improved our grid fluid solution further and are proud to present Hybrido for RealFlow 2014! Hybrido is a fluid solver based on the so-called “FLIP” concept. ”FLIP” stands for “Fluid Implicit Particles” and describes the technology behind this approach. In FLIP solvers, the particles carry the velocity information. The particle-grid approach is very fast, because it requires only a very small number of time steps per frame, while other solvers have to use more substeps to make the fluid stable. Increased simulation speed is just one positive side-effect. Since FLIP solvers are faster it is also possible to run simulations with drastically increased particle counts. With Hybrido you can work with 20 million, 50 million or even more particles within a reasonable time frame. All this results in a higher level of detail and allows you to simulate very fine surface structures and turbulent fluid-object interactions. This state-of-the art technology is combined with Hybrido's easy-to-use workflow. Therefore we have named the combination of our own technology and the traditional concept “HyFLIP”.

Hybrido does not use a fixed domain and the node can be placed anywhere in the scene. When you add a grid fluid domain to your scene you will see a plane with small cubes at its corners representing the smallest cell size. The square indicates the domain's projection plane and shows you how the displacement will be mapped on the fluid, for example. Another field of application is the “Open boundaries” option of the “Hybrido Mesh”. With this mode it is possible to cut away unwanted or unnecessary parts of the mesh according to the plane's position in space. When you start the simulation you will see an adaptive domain around the grid fluid particles that moves with the fluid. The domain’s boundary and grid size is only visible during simulation.
