CD-adapco公司开发的新一代通用热流体分析软件:CD-adapco Star-CCM Plus and Cad Series v2.10.013)，STAR-CD/STAR-CCM+ 两届世界一级方程式锦标赛总冠军获得者F1雷诺车队的选择CD-adapco，2001年，CD-adapco开始了与雷诺F1车队的合作，为其提供世界一流的CAE仿真软件。CD-adapco提供的先进CFD软件“STAR-CD&STAR-CCM+”应用到了雷诺－R26发动机和底盘的设计中。应用模拟软件“STAR-CD&STAR-CCM+”雷诺F1发动机性能和空气动力特性获得极大提高，雷诺F1将CD-adapco的CFD软件成功的运用到了车体性能开发上。 

「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。

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+ V2.10: Multiphase Flow and More

New York and London, November 09, 2007

CD-adapco announces the release of STAR-CCM+ V2.10, the latest version of their engineering process oriented Computational Fluid Dynamics software. Maintaining a demanding four-monthly release cycle, the latest version of STAR-CCM+ includes many enhancements in terms of usability, CAE process and physical modelling capability.

Multiphase Flow

Among many new features, STAR-CCM+ V2.10 introduces a Lagrangian multiphase flow capability. From calculating the impact of rain droplets on the windscreen of a car, to predicting the erosive effect of small particles of sand carried in an oil pipeline, the Lagrangian models allow users to simulate the transport of solid particles, liquid droplets or bubbles of gas by a background fluid. The trajectories are calculated from the inertia, hydrodynamic drag, and gravitational forces acting on each of the particles, droplets or bubbles (known collectively as discrete phases), for both steady and unsteady simulations.

CD-adapco’s VP of Product Management, Jean-Claude Ercolanelli explains:

“From the beginning, a key aim of our development program was to make STAR-CCM+ the industrial code of choice for multiphase applications. In the past twelve months we’ve partly achieved that goal, with the introduction of what is widely regarded as the most comprehensive free-surface modeling capability available in a multipurpose CFD code. The introduction of Lagrangian multiphase into STAR-CCM+ V2.10 is also a significant milestone, enhancing an already recognized capability for efficiently solving large and complex problems.”

“In developing the Lagrangian models we have leveraged twenty years of experience as the leading provider of CFD to the automotive industry, to provide an efficient framework for tackling difficult problems - such as vehicle soiling, or erosion in long pipelines – which, although previously possible in principal, have proved difficult to solve in practice,” says Ercolanelli. “STAR-CCM+ V2.10 brings the routine solution of these multiphase problems, and many others, within the reach of every CAE engineer.”

The multiphase capability of STAR-CCM+ V2.10 is further enhanced with the addition of a compressibility option for free-surface calculations that will allow users to simulate the progress of pressure waves through liquids and to consider the influence of compressibility in regions of mixed vapor and liquid, in which the speed of sound is often lower than in either the liquid or vapor phases individually.

More

“Based around a single integrated process that includes automatic surface repair and solution-efficient polyhedral meshing, STAR-CCM+ already provides the fastest, most automatic route from complex CAD to CFD solution,” says Jean-Claude Ercolanelli.  “For STAR-CCM+ V2.10 we have continued to focus our efforts improving the capability to handle very large size models,  speeding up and refining that process by introducing additional capabilities for managing surface regions, and by providing a new boundary mesh extrusion capability"

Although STAR-CCM+’s surface wrapping capability automatically repairs complex or ‘dirty’ imported CAD, a typical first stage in performing a simulation can be to group specific areas into contiguous regions that are used to prescribe boundary conditions. In STAR-CCM+ V2.10 that process is improved with Boolean operations on surface regions: adding, subtracting or intersecting multiple surface areas to create the required leak-free fluid domains.

The boundary mesh extrusion capability is useful for offsetting the boundary mesh to generate ducts or to extend the computational domain. In both cases the extruder-mesher generates high-quality prismatic elements that are conformal with the volume mesh.

This release also features the addition of a dedicated heat exchanger model for use in underhood thermal management simulation.

The benefit brought by the parallel client / server architecture has also been reinforced to enable true collaborative teamwork.  Multiple STAR-CCM+ clients can now connect on the same STAR-CCM+ server and interact together for their design reviews phases.
