CD-adapco JAPAN Co., Ltd.（以下简称CDAJ）于2006年10月在以日本为代表的东亚各国同时发行由CD-adapco公司开发的新一代通用热流体分析软件「STAR-CCM+」的最新版本v2。
「STAR-CCM+」加入了CD-adapco特有的多面体网格技术、操作界面简单易用，是热流体分析工程师强有力的工具。多面体网格（polyhedral）生成方法不仅更快捷、简单，而且相对于四面体网格(Tetrahedral)，耗费更少的内存便能够得到更高精度的分析结果。
「STAR-CCM+ v2」界面非常友好，对表面准备，如包面（surface wrapper）、表面重构(surface re-mesh)及体网格生成（多面体-polyhedral、四面体-tetrahedral、六面体核心网格-trim）等功能进行了拓展，且在并行计算(HPC)上取得巨大改进；不仅求解器可以并行计算，对前后处理也能通过并行来实现，大大提供了分析效率。在计算速度方面，比上一版本v1成功实现了在64位LINUX机器上计算速度提高20%的目标。在计算过程中可实时监控分析结果（如矢量、标量和结果统计图表等）的功能，同时实现了工程问题后处理数据方面的高度实用性、流体分析的高性能化、解析对象的复杂化、用户水平范围的扩大化。为了满足新一代CFD模拟要求，此求解器采用了连续介质力学（CCM）分析新方法，不仅可进行流体分析，还可进行结构等其它物理场的分析。目前 STAR-CCM+正在应用于多达2亿网格的超大型计算问题上，如方程式赛车外流场空气动力分析等项目。
■特征：
简单易用的操作界面
新设计的界面简单易用、分析设定不易出错。从网格生成到矢量、标量及图表等后处理结果的生成都可以用鼠标操作来完成。
搭载了CD-adapco独创的最新网格生成技术
利用独创的最新网格生成技术，在STAR-CCM+强大的前处理界面上，可完成复杂形状数据输入、表面准备－包面（保持形状、简化结构、回避接触、检查泄露等功能）、表面网格重构、自动体网格生成（包括多面体网格、六面体核心网格、四面体网格）等生成网格所需的一系列作业。
采用最新的数值算法
STAR-CCM+支持任意形状的多面体网格，解算器采用连续介质力学（CCM）算法，除进行流体分析外，加入结构等其它物理场的分析功能。在流体分析模方面，全面引入CD-adapco公司已有的非常成熟的通用热流体分析软件STAR-CD中物理模型。利用CD-adapco倡导的多面体网格，可以实现计算性能（相对四面体网格）约3～10倍的提高。
高度实用性工程工具
在STAR-CCM+中采用了服务用户的系统，能够实时监控计算中的结果数据（矢量、标量及统计结果图表），工程师还可将任意分析参数（流量、力、温度等）作为计算收敛条件来使用。
解算器及前后处理器的完全并行化
STAR-CCM+紧扣10亿左右网格的大规模分析为目标，不仅在解算器方面，而且在前后处理器方面也实现了并行化。用户只需在界面上指定机器名和CPU数，就可以全面实现并行处理。
STAR-CCM+ provides the world's most comprehensive engineering simulation inside a single integrated package. Much more than just a CFD solver, STAR-CCM+ is an entire engineering process for solving problems involving flow (of fluids or solids), heat transfer and stress.
CD-adapco today announced the latest release of STAR-CCM+ version 6.04. CD-adapco is the world's largest independent CFD-focused provider of engineering simulation software, support and services.
“CD-adapco has over 30 years of experience in delivering industrial strength engineering simulation to a wide range of industries and application areas. Our purpose is to help our customers to succeed through the application of engineering simulation: driving innovation in product design AND reducing the engineering time and cost associated with bringing those products to market”, explains Senior VP of Product Management Jean-Claude Ercolanelli. “Being simulation engineers ourselves, we understand our users’ challenges and are uniquely placed to help meet them. We designed STAR-CCM+ v6.04 in collaboration with our customers, implementing their requests to improve the coverage, speed and usability of our software solution.”
The release of STAR-CCM+ 6.04 has three specific aims:
to further expand the application coverage through the addition of new and validated physics.
to further improving quality, robustness and speed of our meshing technology
to enhance usability of 3D-CAD, the surface preparation tools, the CAD-Clients, and the visualization capabilities.
- Eulerian Multiphase
Heat and mass transfer between phases have been added to the existing Eulerian multiphase capabilities. These new features, in combination with a range of new phase interaction options, allow the simulation of wider range of situations. Also added in v6.04 is the option for phase permeable walls opening up the possibility of simulating collection efficiency on boundaries, a key requirement for the study of vehicle soiling, icing prediction on aircrafts. The Eulerian multiphase model may now be used to study the collection efficiency on aircraft.
- DEM bonding and breaking
The Discrete Element Modeling (DEM) can be used to simulate the motion of the granular flow of sand, food particles, metal powders, plant matter, capsules and slurries, etc. In STAR-CCM+ v6.04 this model is enhanced with ability to simulate particle bonding – “clumping” – and breaking under constraint , as well as particles connected by flexible bonds.
- Liquid Film formation, transport and stripping
The accurate simulation of liquid sprays requires the ability to predict what happens when droplets from the spray interact with a solid surface. The STAR-CCM+ v6.04 release includes a new model to predict the formation and transport of a thin liquid film on a solid surface, and its subsequent stripping and break-up under aerodynamic forces. The new fluid film model may be used to study the deposition and transport of thin films.
- Parallel meshing
The STAR-CCM+ v6.04 release includes parallel meshing capability. Available initially for the polyhedral and prism layer meshers, the parallel meshing capability delivers significant reductions in both memory requirement and meshing time.
- Unlock the full power of STAR-CCM+ from within Autodesk Inventor
New in STAR-CCM+ 6.04, the Inventor CAD client allows you to leverage advanced simulation capabilities from the comfort of the Autodesk Inventor environment. With full parametric associativity, boundary setup and both polyhedral and trimmed cell meshing, the CAD clients allow analysis to be seamlessly integrated into your engineering design process. The STAR-CCM+ CAD clients are also available for CATIA V5, SolidWorks, Pro/E and NX.
