RealFlow - 流体动力学模拟软件

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，可以计算真实的运动物体的运动，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。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功能

 

刚性的

这种材料类型用于模拟刚性、不可变形物体的行为。刚体是RealFlow的CPU加速Dyverso多物理场技术的一部分。

 

 

粒状

RealFlow的颗粒解算法允许您模拟成堆的沙子、湿雪、滴落的盐、冰雪片和很多其他材料。颗粒是RealFlow的GPU加速Dyverso多物理场技术的一部分。

 

 

弹性体

这种材料类型用于模拟软体、胶状物甚至布料的行为。Elastics是RealFlow的GPU加速Dyverso多物理场技术的一部分。

 

 

多物理场

在单个模拟引擎下创建和组合不同的材料，如液体、颗粒物质或刚体和弹性体。RealFlow的高性能Dyverso技术采用GPU加速，可让您对模拟进行控制。

 

 

粘弹性

例如，粘弹性材料是泡沫材料或硅基材料的选择，但肌肉、一些果冻状物质或某些涂料也具有这种特性。粘弹性液体是RealFlow的GPU加速Dyverso多物理场技术的一部分。

 

 

CARONTE

RealFlow的全功能多线程人体动力学引擎被命名为“Caronte”。刚体具有快速准确的碰撞和自然的行为。软体支持塑性和弹性自由形式变形—即使是高分辨率网格。

 

 

流体表面

RealWave网格可以通过对象、粒子和很多可自由组合的波浪发生器来影响和变形，以获得高度逼真的海洋表面。其他功能包括置换贴图的导出、波峰飞溅的创建、自定义几何形状的支持以及具有下游力的漂浮体模拟。

 

 

文本工具、对象

编辑器可让您创建文本元素并在模拟中使用它们。RealFlow的对象可以变成刚体、弹性体或软体；它们还充当液体模拟的容器或障碍物。样条曲线在RealFlow中创建或作为SVG文件导入，例如用于粒子发射或自定义力。

 

 

外力

通过易于使用的守护进程引入力量。很多力量可以被缩放、限制和限制以控制它们的范围和行为。守护进程的例子有重力、引力、风、涡流、阻力或基于样条的力。还可以通过Python、C++和Graphs（RealFlow的基于节点的编程系统）引入自定义力。

 

 

渲染

导入场景、添加流体并从RealFlow渲染它们的简单步骤。适用于静止帧或动画序列。由基于物理的渲染引擎提供支持：Maxwell Render。

 

 

网格

RealFlow的网格引擎速度很快，并且支持基于粒子和网格的流体。网格存储年龄或速度等数据，并且可以通过过滤器对其进行细化。可以使用裁剪和多边形优化，以及用于数据交换的各种行业标准格式。可以通过置换贴图增强网格流体网格。

 

 

绘形工具

RealFlow具有用于在粒子流体模拟中创建顶部飞溅和填充孔洞的工具。后者关系薄的、粘性的流体并支持卷须结构的形成。

 

 

行业标准文件

RealFlow能够读取和写入包含粒子和几何体的Alembic文件。集成的拼接工具将序列中的各个Alembic文件组合到一个文件中。此外，RealFlow可以读写带有体积数据的OpenVDB和Field3D文件。

 

 

网络模拟

RealFlow使用“独立计算域”(IDOC)通过网络分发模拟。独立的“作业管理器”和“作业节点”应用程序有助于管理和组织模拟。开放的C++插件架构可以自定义将项目发送给manager的过程。可以使用每个网络浏览器或内置面板监控模拟进度。

 

 

编程接口

编程变得更简便。在RealFlow的“Graphs”系统中，程序是通过连接具有预定义函数的节点创建的，并有助于完成全部任务，例如场的快速操纵、空间粘性、自定义力或图像处理。RealFlow提供与Python 2.7和C++的接口。

 

 

【英文介绍】

 

RealFlow is a fluid and dynamics simulation tool for the 3D and visual effects industry, developed by Next Limit Technologies in Madrid, Spain. This stand-alone application can be used in conjunction with other 3D programs to simulate fluids, water surfaces, fluid-solid interactions, rigid bodies, soft bodies and meshes.

 

Features:

RIGID

This material type is used to simulate the behaviour of rigid, non-deformable bodies. Rigids are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

 

GRANULAR

RealFlow's granular solver allows you to simulate piles of sand, wet snow, trickling salt, icy flakes, and many other materials. Granulars are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

 

ELASTICS

This material type is used to simulate the behaviour of soft-bodies, jelly-like substances, and even cloth. Elastics are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

 

MULTI-PHYSICS

Create and combine different materials like liquids, granular substances, or rigid and elastic bodies under a single simulation engine. RealFlow's high-performance Dyverso technology is GPU-accelerated and gives you unmatched control over your simulations.

 

VISCOELASTIC

Viscoelastic materials are, for example, the choice for foamy or silicone-based materials, but also muscles, some jelly-like substances, or certain paints behave that way. Viscoelastic liquids are part of RealFlow's innovative, GPU-accelerated Dyverso multi-physics technology.

 

CARONTE

RealFlow's fully-featured, multi-threaded body dynamics engine is named“Caronte”. Rigid bodies feature fast and accurate collisions, and a natural behaviour. Soft bodies support plastic and elastic free form deformation – even with high-resolution meshes.

 

FLUID SURFACES

RealWave meshes can be influenced and deformed through objects, particles, and many – freely combinable – wave generators for highly-realistic ocean surfaces. Other features are the export of displacement maps, creation of crest splashes, support of custom geometry, and the simulation of floating bodies with downstream forces.

 

TEXT TOOLS, OBJECTS

An editor lets you create text elements and use them in simulations. RealFlow's objects can be turned into rigid, elastic, or soft bodies; they also act as containers or obstacles for liquid simulations. Splines are created inside RealFlow or imported as SVG files, e.g. for particle emission or custom forces..

 

EXTERNAL FORCES

Forces are introduced through easy-to-use daemons. Many forces can be scaled, bounded, and limited to control their scope and behaviour. Examples for daemons are gravity, attraction, wind, vortices, drag, or spline-based forces. It also possible to introduce custom forces through Python, C++, and Graphs – RealFlow's node-based programming system.

 

RENDER

Easy steps to import your scene, add the fluids and render them out from RealFlow. Valid for still frames or animation sequences. Powered by the most advanced physically-based render engine: Maxwell Render.

 

MESHES

RealFlow's mesh engines are fast, and support particle- and grid-based fluids. The meshes store data like age or velocity, and they can be refined through filters. Clipping and polygon optimization is available, as well as various industry-standard formats for data exchange. Grid fluid meshes can be enhanced through displacement maps.

 

SHAPING TOOLS

RealFlow has tools for the creation of crown splashes and the filling of holes in particle fluid simulations. The latter one cares for thin, cohesive sheets of fluid and supports the forming of tendril structures.

 

INDUSTRY-STANDARD FILE

RealFlow is capable of reading and writing Alembic files with particles and geometry. An integrated stitching tool combines individual Alembic files from sequences to a single file. Furthermore, RealFlow reads and writes OpenVDB and Field3D files with volumetric data.

 

NETWORK SIMULATIONS

RealFlow uses“Independent Domains of Computation” (IDOCs) to distribute simulations over a network. Separate “Job Manager”and“Job Node”applications help to manage and organize simulations. An open C++ plugin architecture makes it possible to customize the process of sending projects to the manager. The simulation progress can be monitored with every web browser or a built-in panel.

 

PROGRAMMING INTERFACES

Programming made easier. In RealFlow's“Graphs”system, programs are created by connecting nodes with pre-defined functions, and help to accomplish almost any task, e.g. fast manipulation of fields, spatial viscosity, custom forces, or image processing. RealFlow offers interfaces to Python 2.7 and C++.
