CST MWS mesh設置問題

在圓柱側面上做貼片天線仿真時出現這樣的錯誤：
42 mesh cells are represented in staircase mode and have been filled with PEC
請大神指教是由于什么原因導致的。

這個沒有遇到過，沒法幫你了、

加密網格吧@@

2樓正解
加密試試

請學會使用軟件的幫助文件。CST MWS幫助文件《Mesh Problem Handling》。

"xxx" mesh cells are represented in staircase mode and have been filled with PEC/PTC.
"yyy" mesh faces are represented in staircase mode and have been filled with PEC/PTC.
Depending on the chosen hexahedral solver this warning might appear. It means that within a mesh cell or a mesh face a certain geometrical configuration cannot be used to run the solver correctly. Therefore these cells or cell faces are filled with PEC or PTC depending on the chosen problem type. However, in many cases these filled cells do not influence the simulation results significantly. The staircase based cells can be seen in the mesh view.

Solution:

Please make sure that the mesh is not too coarse at locations where the staircase based cells appear.
Depending on the chosen problem type, please activate the "Use TST cells" checkbox if provided in the "Mesh Properties - Hexahedral->Specials...->Advanced" dialog box.

謝謝 大神 向您鞠躬。。

老大，你是怎么找到《Mesh Problem Handling》呢？你給出該幫助文件的名字，我可以search到，但是如果您老人家沒給，我們該怎么自己去找呢？

PS：做論文的過程中，如果想查一個概念的準確定義，應該去哪里查呢？比如Bonding Wire。。。論文中的Introduction都是說這個東西可以用來干什么，多么好，卻沒有準確的定義。。。

最一開始的時候，CST MWS 2012的message會提示你看這個文件
或者可以在Mesh Generation Overview里的See Also里面鏈接到這個文件。
Search也是可以的，用關鍵字（比如：represented、staircase或者filled）就可以在Help里的search里面找到這個文件。

到現在在論壇里寫這個文件名已經都背下來了……。總結：無他，唯手熟耳……。

查名詞概念，如果只是自己了解，內事問百度、外事問谷歌、學術問維基。如果要在論文里解釋，那么就必須要找“正規”的reference，基本概念找book，比較新的學術概念首選journal，次選proceeding。
