About 200 hundred years ago, the first industrial revolution saw the transition from bio-fuel-powered, hand production methods to new, factory-based, machine-aided, fossil-fuel-powered manufacturing processes. This was a major turning point in history, which influenced, to some extent, every aspect of daily life.
Steve MacDonald is honored for creating a blueprint for software and tech-based companies on Long Island to become global success stories.
Thermal Modeling Approaches for Printed Circuit Boards (PCBs)
Every electronics assembly includes at least one printed circuit board (PCB) whose primary purpose is to provide electrical connections among chips and connectors. PCBs range in size from a few millimeters across and a fraction of a millimeter thick (such as in a smart watch), to hundreds of millimeters across and several millimeters thick. Printed circuit boards include electrically and thermally conductive layers, often made of copper, sandwiched between thicker dielectric layers which are minimally conductive. Because of their physical size, presence of layers of copper traces, and...
使用流体固体相互作用 (FSI) 扩展多学科分析领域
【内容介绍】 从随风摇摆的树枝到飞机飞过大西洋时机翼产生的屈曲,真实世界中流体和固体在各个地方和谐互动。然而,在虚拟的工程模拟世界中,却很少出现和谐一致的情形。尽管存在着内在联系,但是结构分析和流体动力学长期以来一直都是独立的学科,而变形结构和流动流体之间的互动通常仅得到最低层次的研究。 但是,随着创新的模拟工具让我们对流体和固体之间的互动有了更多了解,帮助工程师更快地创造出更好的设计,这一情况正在改变。 本次网络研讨会展示出单个集成用户界面内的模拟如何通过多种技术应用于执行FSI分析,包括利用突破性的新有限元求解器。 【主讲人】 刘文东,工程师 【关于 Webinar 】 Webinar是一种通过网络媒体进行的技术研讨活动,我们通过WebEx系统在网络上提供技术交流。用户只需要在计算机上连接网络就可以聆听和观看技术报告以及产品功能的展示。我们会提供网络和对方付费的电话号码实现声音的传输。Webinar登录的详细方法,会在注册后的邮件回复中进行说明。 ※从本页面注册后,数分钟后您的注册邮箱会收到自动发送的邮件回复,请注意查收。如果长时间没有收到邮件回复,请与我司联系。 ※注册时,请务必使用所在单位的邮箱进行注册;公共邮箱注册的情况,有可能会被拒绝,请了解。
Virtual Powertrain Design: Simulating Engine Operation
Original Equipment Manufacturers (OEMs) are increasingly turning to computer aided simulation to help improve engine performance. They are finding that simulation-based design offers the greatest potential for cost savings, as the engine can be first broken down into different key components which influence performance. These key components vary from the intake port flow, in cylinder combustion process, to coolant flow, piston cooling, and even the oil flow patterns in the engine. There are certain test criteria that have been contingent on using only physical testing in the product...
STAR-CCM+ v10.06版本新功能介绍
【会议信息】 时间:2015年11月25日下午3:00-4:00 费用:免费(需事先注册) 语言:中文 注册方法: 希望参加本Webinar的客户,请从本页面的注册窗口进行注册。 【内容介绍】 CD-adapco公司很高兴的宣布,STAR-CCM+ v10.06版本已于2015年10月28日正式向全球用户发布。该版本最大的特色是增加了对一个新的工程学科计算——流变学的模拟功能,这样使得我们将多学科设计探索(MDX)这一CAE行业创新的使命又向前迈进了一步,帮助用户更快更好的寻找更优设计。 计算流变学功能进一步扩展了STAR-CCM+多学科求解的范围,能够解决粘性和粘弹性占主导的力学问题。现在可以应用于解决静态混合器的流动、流入容器、具有显著发热的泵送泥浆以及型材和材料加工。这一求解功能是建立在与v10.04发布的计算固体力学相同的有限元(FE)架构上的。 STAR-CCM+ v10.06其它主要新功能以及对已有功能的增强列举如下: 双向流固耦合:通过STAR-CCM+单一用户界面更容易实现紧密耦合,提高计算精度; 手动表面修复易用性增强:无论有经验的工程师还是新手,都能为其节省大量的工程时间; 基于查询的选择:使操作、显示和零部件的过滤和选择更加简单直观; 运用Parts-based的工作流程提高了基于Parts的Interfaces的性能和扩展性,...
This article details results from the numerical simulations on the NASA Trapezoidal Wing geometry, focusing on the high lift prediction using the CD-adapco solver STAR-CCM+. Computations and validation were based on the guidelines and experimental data provided for the 1st AIAA High Lift Prediction Workshop (HiLiftPW-1) to assess the numerical prediction capability of STAR-CCM+ for high lift configurations.
In this report, the performance of the Standard Cirrus glider is simulated using STAR-CCM+. To calculate the important transitional boundary layer flow, the Ȗ-Reș transition model is used. The study is performed to test the quality of the transition model and to create a validated reference model of the glider’s performance in steady level flight. The validated model will in future studies be used to improve the performance and handling quality of the glider and serve as a reference model for other simulation tools.
STAR-CCM+ is developed to be accurate, efficient, easy to use, and, thanks to its rapid release cycle of three major releases each year, to grow with the needs of our users in mind. We are always improving the technology and capabilities to better solve the problems facing the aerospace industry. This article highlights a few recent and upcoming capabilities.
