Today，the auto industry must move away from the traditional trial-and-error methodology of crash testing and embrace simulation-based design. To help designers and engineers achieve this take advantage of the latest simulation technology,ESI and Intel hace been working to bring leading simulation software to market that will help companies to innovate faster by reducing the need for real prototypes through collaborative engineering.
Specifically, the research and development teams at ESI and Intel have been working to optimise ESI's Visual Environment V3.0 to take advantage of Intel's multi-core processors,using software tools(Intel VTune and Intel Thread Checker).
This joint Intel/ESI development means users can now enjoy enhanced computing performance, better cost efficiency and more choice with regards to the size of the crash model.
The development also provides more accurate simulations. Data-processing time is up to 2.79 times faster for huge crash models(10 millon elements) on Visual Environment V3.0, as optimised on the latest multi-core Intel Xeon processor.
ESI's integrated solution underpins a proven engineering simulation environment based on openness and extended interoperability with tier CAE and ESI's solvers. This sharing of resources between ESI and Intel amounts to a significant step forward in realistic simulations that use a minimum of 10m elements for crash simulation.
The first results point to a performance boost of up to 250% in data processing from VE 2.5 to the VE 3.0 optimised on the latest dual-core Intel Xeon Processor 5100 Series , as well as more than 4GB allocated in memory using Windows XP 64bit on the latest multi-core Intel Xeon processor . These outstanding scores produce more accurate simulations , mainly due to a refined model which allows the investigation of critical zones, such as that made by a German carmaker using the multi-scale coupling option of Pam-Crash 2G to introduce detailed information results from casting into crash-model simulation.
"Intel is very pleased that, through our collaboration, ESI Group has used our software development tools to optimise Version 3.0 of Visual Environment to provide new levels of performance on our Dual - Core Intel Xeon Processor 5100 Series ," says Stephane Negre, Intel EMEA global software relations manager . "ESI Group's customers can now load models of millions of elements .We will carry on working with ESI Group in developing new platforms to anticipate the future customer's needs."
"This partnership with Intel enables ESI Group to overcome environmental limits by opening up new opportunities to solvers to deliver realistic simulations . Up to now ,our customers were obliged to build compute models dedicated to several types of crash simulation . Thanks to these excellent results , engineers can use a unique crash model that covers the crash and safety simulation domain as a whole ," says Jean - Louis Duval ,ESI Group worldwide business manager for enterprise integrated solutions .
The next step will be to take advantage of Intel multi-core technology in order to provide a multi-thread environement, which will deliver the best in -class performance solution.

今天，汽车工业必须摆脱传统的以反复试错为方法的碰撞实验，接受基于仿真的设计。为了帮助设计师和工程师达到这个目标，并利用最新的仿真技术，ESI集团和英特尔公司一直致力于把领先的仿真软件投入市场，这将有助于公司加快创新速度，通过工程师协作减少对真实原型需要。
具体而言，ESI集团和英特尔公司的研发团队利用英特尔性能分析器（Intel VTune）和英特尔线程检查器（Intel Thread Checker）等软件工具，一直在努力优化设计ESI集团的视觉环境软件3.0版，(ESI's Visual Enviroment V3.0)，以利用英特尔公司的多核心处理器(Intel’s multi-core processors）。
此次英特尔/ESI的联合开发意味着用户现在可以享受更强的计算性能，更好的成本效益和对于碰撞模型尺寸的更多选择。
这项开发也为用户提供了更为准确的模拟。由于在最新的多核英特尔至强处理器（multi-core Intel Xeon processors）上优化，在视觉环境3.0版（Visual Environment V3.0）中，大型碰撞模型（1000万个单元）的数据处理时间可提快至2.79倍。
WSI的整合式解决方案基于CAE和ESI的解决者之间的开放性和扩展互操作性，加强了行之有效的工程仿真环境。使用最低限度的10兆单元来做碰撞仿真，ESI和英特尔的这次资源共享等同在真实的仿真中向前迈出的重要一步。第一项成果是，在最新的双核英特尔至强处理器5100系列（dual-core Intel Xeon Processor 5100 Series）上优化，以及在有超过4GB分配内存、采用windows XP64位、最新的多核英特尔至强处理器（multi-core Intel Xeon processor）上优化，从视觉环境2.5版（VE2.5)到视觉环境3.0版（VE3.0)，在数据处理上性能提升高达到250%。这些显著的成绩产生更加准确的模拟，这得主要功于允许关键区域调查的精确模型，例如像德国汽车制造商做的那样，采用Pam-Crash-2G软件（ESI推出的一个软件，是一个应用于冲击、碰撞和安全性专业领域的虚拟测试解决方案）中的多尺度耦合选项，来引入铸件的详细信息到碰撞模型仿真。
“英特尔公司非常高兴地看到，通过我们的合作，ESI集团已经利用了我们的软件开发工具，在我们的双核英特尔至强处理器5100系列（multi-core Intel Xeon processors 5100 Series）上，来优化3.0版的视觉环境（Visual Environment），以提供新水平的性能。“英特尔欧洲、中东和非洲公司（Intel EMEA)全球软件事务经理斯蒂芬 尼格（Stephane Negre）说，”ESI集团的客户现在可以担负数百万单元的模型的仿真。我们会继续努力做好工作，与ESI集团开发新的平台，以抢占未来客户的需要。“
”和英特尔的这一伙伴关系，通过开辟新的机会给解决者来交付真实仿真，使得ESI集团客服环境的限制。在此之前，我们的客户不得不建立计算机模型，专责集中类型的碰撞仿真。而现在由于这些出色的成绩，工程师们可以使用一个唯一的涵盖了碰撞和安全仿真领域，并作为一个整体的碰撞模型。“ESI集团负责企业集成化解决方案的全球事务经理珍妮 路易斯 杜瓦尔（Jean Louis Duval）说。
下一步将充分利用英特尔多核心技术，以提供一个多线程环境，这将得到实现最好的、一流的性能的解决方法。
