IEEE MTT-S INTERNATIONAL MICROWAVE SYMPOSIUM, HONOLULU, HI - June 5, 2006 - Ansoft Corporation (NASDAQ: ANST) announces the release of HFSS? v11. This release of Ansoft's flagship product features new technology that delivers even greater accuracy, capacity and performance than before. HFSS v11 includes new higher-order hierarchical basis functions combined with an iterative solver that provides accurate fields using smaller meshes and thus more efficient solutions for large multi-wavelength structures. A new fault tolerant, high-quality finite element meshing algorithm allows HFSS to simulate very complex models two to five times faster using half of the memory compared to previous versions.
"The new technology in HFSS v11 allows our customers to perform massive simulations of structures that were simply too large to solve previously," said Dr. Zoltan Cendes, Ansoft's chairman and chief technology officer. "Designers of high-frequency and high-speed components now have the ability to explore electromagnetic performance over a range of dimensions, orientations, material parameters and frequencies and hence to gain design insights that were not possible before."
HFSS is the standard for 3D full-wave electromagnetic field simulation, a critical aspect in designing high-performance electronic devices that are more portable, smaller in size and operate at higher frequencies. These devices include RF/microwave components, on-chip passives, PCB interconnects, antennas and IC packages.
The dynamic link between HFSS and the company's advanced, combined frequency- and time-domain circuit simulator Nexxim?, and Ansoft Designer?, the company's integrated schematic and design management front-end, creates a powerful electromagnetic-based design flow. This design flow enables users to merge complex, highly nonlinear transistor-level circuits with 3D full-wave accurate component models to solve challenging high-performance electronic designs.
Highlights of HFSS v11
* Higher-order, hierarchical basis functions
* Iterative solver
* Enhanced port solver
* Floquet ports
* Genetic algorithm to expand optimization choices
* Auto-assign capability for terminals
* Fault tolerant, high-quality finite element mesh generation algorithm

新版本也未必改进太多吧？感觉10和9.2就没有太大区别。
10.0在激励源、边界和建模方面都做了一定的完善。期待11.0版本。
哦.太好了.不知道什么时候能够用上呢.哈哈.
Ansoft发布三维全波电磁场仿真行业标准工具的最新版本HFSS v11，在仿真精度、能力和性能等方面显著改进
2007年6月5日，在夏威夷举行的MTT-S国际微波座谈会上，Ansoft公司隆重发布了其旗舰产品高频结构仿真器的最新版本HFSS v11。新版本应用了多项新技术，在仿真精度、能力和性能等各方面有了很大飞跃。HFSS v11的电磁场求解器采用了更高阶的基函数，与迭代法矩阵求解技术相结合，对于电大尺寸结构问题的求解，网格数量更少，求解更精确和高效。HFSS还采用了新的容错网格剖分技术，能够生成更高质量的有限元网格，与之前版本相比，在仿真非常复杂的模型时不但内存消耗降低了一半，而且速度提高了2至5倍。
“HFSS v11中采用的新技术使我们的客户能够从容地应对那些在过去的版本中因为电尺寸过大而无法求解的问题，” Ansoft公司董事会主席兼首席技术官Zoltan Cendes博士说，“对于高频高速的设计者们而言，新版本能够为他们在研究结构电磁特性时提供前所未有的，对尺寸、方位、材料特性参数和频率等参数在更大的范围内进行设计空间探索的能力。”
HFSS是三维全波电磁场仿真的行业标准工具，广泛应用于高性能电子设备和器件的设计，包括射频/微波元件、片上无源器件、PCB互联结构、天线和IC封装等，这些电子产品的重要的特点是向着便携化、小型化发展，同时应用频率和速度越来越高。
HFSS能够与频域/时域的电路仿真器Nexxim和Ansoft Designer动态链接，提供了方便的原理图集成与端到端设计与仿真数据管理能力，建立了功能强大而高效的基于电磁场的设计流程。HFSS提供的三维结构高精度全波器件模型，能够直接嵌入Ansoft Designer/Nexxim中，与复杂的强非线性晶体管级电路结合在一起，进行电路、系统和电磁场协同设计与仿真， 实现高性能的电子设计。
HFSS v11的主要功能增强包括：
-- 求解器中增加更高阶的基函数求解
-- 迭代法矩阵求解器
-- 改进了端口求解器，支持Floquet 端口
-- 优化算法中增加了遗传基因算法（Genetic algorithm）
-- 自动定义终端
-- 容错技术及高质量的有限元网格生成算法
-- 分布式求解（DSO）支持插值扫频、参数化扫描、敏感度分析和统计分析
-- 改进了用户界面和动态链接功能
HFSS v11支持的操作系统包括：
Microsoft Windows(R) 2000 Professional, Windows XP Professional, Windows XP x64 Edition, Windows Server, Red Hat Enterprise Linux(R) v3, Solaris(R) 8 and Solaris 9. 详细信息，请联系当地Ansoft代表处
受教了!
虽然用的不熟悉 但是还是下来看看 功能如何？
与之前版本相比，在仿真非常复杂的模型时不但内存消耗降低了一半，而且速度提高了2至5倍。
有这样的事？
那真的是很值得期待了。
如果hfss11在仿真大带宽方面也能做的更好的话那就更完美了。
大家谁用过啊？如果真的能在电大尺寸方面改进那就太好了
期待着
现在运算量大的自己的机子跑不起来
只有到工作站上面算
太麻烦了
