We will cover everything from swimming creatures, body liquids (such as blood, slime, and tears), wounds, and even tearing effects for skin and flesh. Studying these effects will become much easier if we understand how fluids are being processed and simulated in Realflow and similar programs, because that will enable us to choose the perfect tools for each scenario. Recently, programs such as Naiad, Houdini, and Realflow implemented new fluid simulation techniques which depend on both traditional fluid simulation methods, SPH, and voxel-based fluids.

This new fluid technique is called the FLIP solver. It focuses on the advantages of the previous techniques and improves upon them to produce faster, more stable liquids, a massive amount of particles, and fewer sub-steps to process. Realflow's copy of the FLIP solver is called Hybrido, and Hybrido made the use of fluids a very easy task compared to what was needed before and it is more powerful than it has ever been before. We will study the three solvers, focusing mainly on the two major ones in Realflow (SPH and Hybrido). We will determine the uses, advantages, and disadvantages of both, and we will test them in extreme scenarios through their interaction with creatures.
