CD-adapco公司开发的新一代通用热流体分析软件

「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。

特性：

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。

CD-adapco has released version 7.04 of its STAR-CCM+ software, which the company says will help users accelerate product development processes by performing more simulations in less time.

The introduction of Multi-part Solids improves the scalability of thermal simulations that previously involved multiple parts and materials. The ability to use a single solid continuum makes thermal simulation problems easier to set-up, and increases the speed of calculation, the company says.

The new Solar Loads Calculator allows solar radiation to be automatically specified by latitude, longitude, time and date, with an additional factor to account for changing skies. These parameters are updated automatically during transient analysis to facilitate the simulation of occupant comfort.

Customers can use Optimate and Optimate+, which are add-on modules for STAR-CCM+ that directly employ process automation and design optimization technology from Red Cedar. The Optimate solution, which includes CD-adapco s Power Token software licensing, allows engineering designers to set up, execute, and post-process design exploration studies such as parameter sweeps and/or DOEs. Optimate+ adds the capability to perform automated design optimization studies using the SHERPA algorithm from Red Cedar.

Further enhancements in speed come from the introduction of a newly improved mesh morpher, which delivers a speedup of up to four times more than previous releases.

The introduction of Implicit Co-simulation between STAR-CCM+ v7.04 and Abaqus v6.12 has increased the stability of highly non-linear fluid-structure-interaction problems, speeding up the solution time by use of typically larger time-steps.

A new Granular Flow model enhances the Eulerian multiphase capabilities of the solution by facilitating the simulation of highly packed materials, accounting for the frictional stress and particle drag. This capability opens up applications such as fluidized beds, drilling, slurry flows, and granular transport to simulation.

The Overset Mesh feature is expanded to allow regions to travel to, and beyond, the boundary of the domain, improving the flexibility of overset grids and allowing the simulation of very close moving bodies, such as store separation.
