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 STAR-CCM+Box Includes Polyhedral Mesher
LONDON, England, March 17, 2005 - CD-adapco, the leading provider of full-spectrum and CAD-embedded Computational Fluid Dynamics, has announced the release of the world's first fully integrated process for polyhedral CFD. The first official release of the STAR-CCM+ Box Set combines CD-adapco's technology leading STAR-CCM+ solver with STAR-Design, which includes the world's first commercially available polyhedral mesher.
STAR-Design, CD-adapco's fully functional parametric solid modeler, allows polyhedral meshes to be created at the click of a button. Based on the same Parasolid kernel that powers many leading CAD packages, STAR-Design is both powerful and easily accessible. Using an intuitive interface, even a casual user can easily build, mesh and run an industrial strength CFD simulation. Using STAR-Design, polyhedral meshes can be easily generated from the created (or imported) CAD geometry at the click of a button.
Extensive validation has demonstrated that polyhedral meshes offer near hexahedral accuracy with all of the automatic meshing benefits of tetrahedra. Professor Milovan Peric, CD-adapco's Director of Technology, explains, “Recent tests have shown that, for equivalent or better accuracy, polyhedral meshes converge up to ten times faster than tetrahedra, typically delivering a speedup of 400 - 500%”, he says, "Polyhedral CFD delivers more for less: more accurate solutions, using fewer cells and ultimately greatly reduced human and computing resources"
Dr Dennis Nagy, CD-adapco's Vice President of Business Development, acknowledges that polyhedral meshing is the first payoff of CD-adapco's investment in solver technology. "While other CFD vendors are content to simply build upon their existing aging software architectures with STAR-CCM+, we decided to go back to the drawing-board and build our solutions upon the most advanced technology currently available", says Dr Nagy. “The arrival of polyhedral meshing represents a watershed for industrial CFD".
"I am confident that the arrival of our polyhedral meshing technology spells the end for tetrahedra as a useful tool for CFD", says CD-adapco President and founder Steve MacDonald. "Tetrahedra - as well as the CFD codes which continue to rely on them - are doomed to become a thing of the past"
