向CST MWS里導(dǎo)入PCB的問題
最近公司給我一個任務(wù)，要我測試一個已投入使用的PCB板的電磁兼容性并給出可行的修改建議。之前我沒有用過CST PCB STUDIO, 參考了Help content后開始上手，覺得遠(yuǎn)沒有MWS來的復(fù)雜和多變，但是還是有問題出現(xiàn)了。
1：關(guān)于把PCB模型導(dǎo)入到PCB時，總顯示導(dǎo)入失?。@示文件夾為空），對方公司提供的是用mental graphic expedetion設(shè)計的12層PCB板，在查閱貴版的過往帖子時，我看到過一個關(guān)于PCB的帖子，說的是好像是大于6層以上的PCB就不能導(dǎo)入PCB STUDIO了，而是要導(dǎo)入MWS，請問是這樣的嗎？
2: 當(dāng)我導(dǎo)入到MWS時，步驟是MWS-->FILE--->IMPORT--->EDA--->ODB++, 然后這時顯示出了PCB文件。大家都知道，為了減少計算時間，在保證精度的情況下，能適當(dāng)減少mesh數(shù)量是一個很好的選擇，而在最終導(dǎo)入到working pad前，會有一個選項 ：create a selection area, 點擊這個后，會出現(xiàn)一個對話框include shapes with distance,此時，我的問題也來了，當(dāng)我輸入一個數(shù)值，并點擊OK后，CST 就沒有響應(yīng)了，我最長等過一天一夜，還是沒有反應(yīng)。請問大家知道這是為什么嗎？另外，大家如果知道如何選取整個PCB的一部分，然后導(dǎo)入的話，請不吝賜教，小弟感謝萬分。
為了大家看的更明白，我上傳一張圖片，勞煩各位啦！
Hi, guys!
Im sorry for explaining my question to you in English because of the my company limitations.. Recently, I've met a problem of importing a PCB (designed by Mental Graphic Expedition )to the CST PCB studio, as the software always warned me with the reason of wrong path and empty folder. Then, I chose to import the PCB model to the CST Micro Wave studio directly and everything was fine until I reached the step of "create a selected area". As everyone knows, to import an entire PCB model to the CST MWS and start the simulation would cost a huge calculation time, and that's why we had such option of reducing the size of PCB model and selecting only the expected area. Ok, when I click "create a selected area" and then a dialog would be poped out and it was "include the distance to the desire trace"(something like that , i cant remember precisely). I inputed a value and click "OK", and now the sofeware would have no response and this situation would last for a day (the longest time i've waited for). I dont know what I've done wrong but if someone here could solve my problem, I would be really grateful!
I will attach a graph of working sheet in order to make my question more clear!
Thank you all guys in advance
12層導(dǎo)入PCBS按理不會出錯，你可以在導(dǎo)入的那個界面看一下help，對于很多的格式還是有更具體的要求的。
PCBS沒用過，沒有建議。
MWS沒導(dǎo)入過ODB++格式，參數(shù)的解釋應(yīng)該都寫在幫助文件里了。
軟件停止響應(yīng)的問題應(yīng)該只能去問CST技術(shù)支持了。
Thank you guys!
The CST German headquarter has sent their contactor to my company just now and these two problems has been solved.
1:About importing the PCB to MWS
He confirmed that it was avaliable to importa PCB with less than 6 layers to the PCB STUDIO for simulations only, and it's better to import it to MWS if you want to do a simulation with a PCB which has more than 6 layers. In my case, the PCB which was designed by Mental Graphic Expedetion should be imported to PCB STUDIO by selecting the path "SIMLAB", NOT "Mental Graphic Expedetion", OR else you can not find the PCB file from the "Mental Graphic Expedetion" folder...
2: When you import the PCB model to the MWS, and if you want to select a small specific area, you should
a: Activate the option "restrict to selected area",
b: Moving your mouse to the PCB graphs showed on the right side and right click,
Now you will see several options. select the option"NEW RECTANGULAR SELECTION", up to now, you can hold the left click and drag the mouse right side down to choose the area you want. (Right click on the other parts outside of the selected area to deavtivate the selected area)
I know it is an individual case which represents little, but I think it is somehow useful if some fresh guys want to use CST to do some simulations of PCB, and sometimes those details of operation are the fundamental steps of using CST. aren't they?:)
Thank you guys again!
There're also graphes for the second question.
樓主的機(jī)器什么情況？PCB模型數(shù)據(jù)多大？
Thanks a lot for your kindly concern, the machine was bought in 2005
500G hard disk,the PCB file (in the form odb++) is 15MI forgot to attach the graph. In fact, the contactor told me that the machine was good enough to run the CST and bascially the shortage of virtual memory would not happen. He only suggested to run less processes while the simulation was on...
英語好棒啊，十分羨慕，
