CST2009版改進(jìn)或新增功能(來自MicroWave Journal)

來源：edatop 更新時間：2024-07-07 閱讀：

1、友好的前端建模，如增加了彎折貼片功能，在天線領(lǐng)域尤為實用，與實際工程上的操作如出一轍，如下圖。
2、增加了Nastran、Gerber和GDSII的導(dǎo)出功能。
3、MWS中頻域有限元求解器采用全新的四面體自適應(yīng)網(wǎng)格，更加逼近原始的光滑模型。如圖，傳統(tǒng)的四面體
網(wǎng)格只是將圓等效為一個近似的正多邊形，而新四面體網(wǎng)格能使圓的邊界更加逼真、精確。
4、新增工作室PCB和CABLE使CST產(chǎn)品線更加完善。
5、真正意義上的純瞬態(tài)場路協(xié)同仿真。

看上去很不錯啊，希望能早點用上它

依照CST以往的慣例,....出了 2009之後,很快就會有 SP1......SP2.......! ：18de

真是很不錯，這些功能很誘人，希望仿真功能也一樣。

呵呵，新版本bug 較多，補丁也多。
