Mentor Graphics Corporation (NASDAQ: MENT) today announced the FloEFD™ [Engineering Fluid Dynamics] v9.0 product suite from the company’s Mechanical Analysis Division (formerly known as Flomerics), with functionality specifically targeted for simulation and analysis of electronics cooling applications. As a “CAD-Embedded” application, the FloEFD suite tightly integrates with all popular MCAD design solutions to enable mechanical designers to easily analyze sophisticated electronic products including those with complex geometries. The FloEFD suite now complements Mentor’s FloTHERM® product line to cover analysis by both the mechanical designer as well as the thermal analysis specialist. With FloEFD, the simulation models are easily and directly generated from the design database while in the MCAD environment, thus enabling a seamless, streamlined design flow for optimum designer...
LMS Imagine.Lab AMESim offers a complete 1D simulation suite to model and analyze multi-domain, intelligent systems and predict their multi-disciplinary performance. Model components are described using validated analytical models that represent the system’s actual hydraulic, pneumatic, electric or mechanical behavior. To create a system simulation model, all the user has to do is use the various dedicated tools to access the required pre-defined components from validated libraries covering different physical domains. LMS Imagine.Lab AMESim can work with a variety of libraries to create a physics-based system model. Using libraries like the Hydraulic Component Design (HCD) and IFP-Engine, LMS Imagine.Lab AMESim software can accurately simulate intelligent system behavior long before detailed CAD geometry is available.Product:LMS AMESim 8.0 Lanaguage:english Platform:Winxp/Win7 Size:195MB
Ansys Products v12.1.1 LinX64正式发布! ANSYS 系列产品 ANSYS 新版本在CAE 功能上引领现代产品研发科技,涉及的内容包括:高级分析、网格划分、优化、多物理场和多体动力学。 立足于拥有世界上最多的用户,ANSYS 12.1.1 Linu 64位 不仅为当前的商业应用提供了新技术,而且在以下方面取得了显著进步: · 继续开发和提供世界一流的求解器技术 · 提供了针对复杂仿真的多物理场耦合解决方法 · 整合了ANSYS 的网格技术并产生统一的网格环境 · 通过对先进的软硬件平台的支持来实现对大规模问题的高效求解 · 继续改进最好的CAE 集成环境-ANSYS WORKBENCH · 继续融合先进的计算流体动力学技术 加速多步求解 ANSYS VT 加速器,基于ANSYS 变分技术,是通过减少迭代总步数以加速多步分析的数学方法。这包括了收敛迭代和时间步迭代或者二者的综合。收敛迭代的例子是非线性静态分析,不涉及接触或塑性,而时间步迭代指的是线性瞬态结构分析,二者组合的例子,非线性结构瞬态或者热瞬态分析。 ANSYS VT 加速器提供了2-10X 的加速比,允许用户快速重新运行模型。具体的加速比受到硬件、模型和分析类型的影响。而且,这个工具在非线性或瞬态分析的参数研究中可以获得5-30X 的加速。在使用ANSYS VT 加速器之前,用户可以作下列类型的改进: · 修改或者增加或移除载荷(约束不能更改,但是数值可以修改) · 材料和材料模型 · 截面常数和实常数 · 几何 ANSYS VT 加速器软件,使用ANSYS MECHANICAL HPC 的授权,可以应用到结构循环对称模态分析以及高频电磁谐分析。ANSYS VT 加速器可以结合ANSYS DESIGNXPLORER VT 技术,实现更快速的参数化研究。 网格变形和优化 对于很多单位,进行优化分析的最大障碍是CAD 模型不能重新生成,特征参数不能反映那些修改研究的几何改变。通过与ANSYS WORKBENCH 的结合,ANSYS MESH MORPHER (FE-MODELER 的新增加模块)可以实现这个功能,甚至更多。 通过网格操作而不是实体模型,ANSYS MESH MORPHER 对于来自于CAD 的非参数几何数据,如IGES 或者STEP,以及来自于ANSYS CDB 文件的网格数据,实现了模型参数化。将网格读入FE MODELER,并且产生对应于该网格的“综合几何”的初次配置。在ANSYS 12.0 Linu 64位,ANSYS MESH MORPHER 提供了四种不同的转换:面平移、面偏置、边平移和边偏置。更多样的配置可以通过以上转换的组合实现。例如,一个圆柱表面的面偏置就等效于变更其半径。 这些转换决定了目标配置并自动定义转换参数。一旦确定,这些转换参数可以通过ANSYS DESIGNXPLORER VT 拟合方法来拟合,如KRIGING 算法、非参数化退火算法和神经网络算法等。一旦拟合完成,可以使用ANSYS DESIGNXPLORER VT 中的能量优化技术找到最优值或者执行6 SIGMA 分析设计。ANSYS MESH MORPHER 为仿真驱动的产品开发打破了优化障碍。 流固耦合 在ANSYS WORKBENCH 中,ANSYS 和ANSYS CFX 技术的集成取得了更大的进步。在12.0 Linu 64位 的ANSYS WORKBENCH 环境中,用户可以完整地建立、求解和后处理双向流固耦合仿真。最新的版本也提供了单一后处理工具,可以用更少的时间获得复杂多物理问题的解决,并且扩展了仿真的应用领域。 利用ANSYS CFX 软件的统一网格接口可以在ANSYS 和ANSYS CFX 之间传递FSI 载荷,所有流固耦合问题的结果的鲁棒性和精度获得了改进。界面载荷传递技术的突破,很明显的好处就在于让同一团队的FEA 和CFD 专家共享信息更方便。在12.0 Linu 64位...
