RealFlow是由西班牙Next Limit公司出品的流体动力学模拟软件。它是一款独立的模拟软件，可以计算真实世界中运动物体的运动，包括液体。RealFlow提供给艺术家们一系列精心设计的工具，如流体模拟（液体和气体）、网格生成器、带有约束的刚体动力学、弹性、控制流体行为的工作平台和波动、浮力（以前在RealWave中具有浮力功能）。你可以将几何体或场景导入RealFlow来设置流体模拟。在模拟和调节完成后，将粒子或网格物体从RealFlow导出到其他主流3D软件中进行照明和渲染。RealFlow在电影、电视剧、广告、游戏等领域均有非常广泛的应用。RealFlow应用的电影有：《冰河世纪4》，《复仇者（2012）》，《洛杉矶之战》等等大型国际电影。

cmiVFX Living Creatures in Realflow Vol 01
cmiVFX launches its latest full feature series training video titled “Living Creatures in Realflow.” In this training video series, we will cover a hot topic in Realflow that has been mysteriously hard to reach through available training courses on internet. It is about how to use liquids and fluids with creatures. The number of scenarios that you can encounter for this are unlimited. 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.
