这个feko怎么样啊？

我还没用过这个软件，不知道效果怎么样?

要看用来做什么了

整体来说还是很不错的，尤其擅长电大尺寸

“尤其擅长电大尺寸”，这要看跟谁比了。如果是跟HFSS比，那确实是挺能算电大的，但是如果碰到了真正的电大尺寸，就只能用PO/GO这些方法了，而这些方法的局限性有多大相信很多人都很清楚。我个人认为FEKO还是挺不错的，和CST和HFSS相比确实很有特点，但是国内的宣传有些过头了，说什么“电大尺寸终结者”，连X-patch和FISC都不敢说这样的话。所以平时在解决不了电大尺寸问题时，就会很窝火。

Xpatch等并不强，算法单一，同样是射线法，应用面还很窄。

现在最强的是feko了，xpatch只是用来初步估计RCS

在我们能买到或down到的软件中，feko是最擅长计算电大尺寸的了，所谓的“真正的电大尺寸“，我觉得算法上还没有完全解决，更别说软件了，只能等以后硬件和算法的发展来解决了
 

忽悠的人太多了。FEKO只是把PO与矩量作了结合，实际电大尺寸还是单纯PO。没那么神。

我也正想用这个软件呢,不知道能不能来的及呀,我还有半年的时间就毕业了,而且我是学俄语.

世界上本没有路，忽悠的人多了，也就成了路。

其实我觉得解决电大尺寸是通过牺牲内存的方式来进行的，如果机子不行，还是做不出来的

你很了解Xpatch? 厉害啊

似乎大家都很了解Xpatch啊，
我不觉得Feko是最强的，现在好多软件超过它，只是FEKO在中国年代多，影响力大，其实在业内这个软件口碑很差的。

是啊，现在很多问题还没有解决

很多的問題?<-- 不知您指的是什麼問題?歡迎提出討論....
難道您認為目前市售的軟件有能力解決嗎?那請提出數據來說服大家...

多谢各位指教，看来要想了解一个软件只有亲自试试了

對..說的好....因為都是商業的東西... 所以有蠻多軟體都暗藏了很多商業的手法..。..其實每一種軟體都要用深入用了才會知道...。

那么怎么也都找不到xpatch来用一下阿

這我不清楚去哪找呢?But, The Xpatch^® toolkit is a set of prediction codes and analysis tools that use the shooting-and-bouncing ray (SBR) method to predict realistic far-field and near-field radar signatures for 3D target models.

Xpatch® Electromagnetic Simulation SoftwareOverview
The Xpatch^® toolkit is a set of prediction codes and analysis tools that use the shooting-and-bouncing ray (SBR) method to predict realistic far-field and near-field radar signatures for 3D target models.
Applications
The Xpatch toolkit is used by the Air Force Research Laboratory and Defense Advanced Research Projects Agency (DARPA) for multiple radar simulation programs. There are over 9000 active licenses across the country in both industrial and government applications using the Xpatch toolkit to produce and analyze scattering data for realistic aircraft, missiles, ships, spacecraft, and ground vehicles.
Features
The Xpatch code suite was rewritten in a C++ object-oriented framework combining the Xpatch 2.4 toolkit versions of XpatchF and XpatchT into a single product. Xpatch toolkit enhancements include:

• Near-field capabilities
• Multiple IGES entities, scattering centers, and hybrid capabilities support.
• Intuitive user interfaces aid in problem setup, model checking, moving components, comparing signatures, and plotting results.
• FISC, a method-of-moments solver using the breakthrough multilevel fast multipole algorithm (MLFMA) fast matrix solver, originally developed at the University of Illinois. More information about the University of Illinois Department of Electrical and Computer Engineering is available at http://www.ece.uiuc.edu/.

Benefits
The Xpatch toolkit is the premier electromagnetic (EM) code suite for predicting and analyzing high-frequency radar signatures. It has evolved and matured through extensive validation efforts with the Air Force Research Laboratory (AFRL).

只是粗劣的估计而已

靠，没有用过就来骂xpatch呀，我又一些xpatch的计算结果，feko差的远了。radebase有人有么，我想要
