一般來說, 若透過 EDA Bridge 匯入 ODB++ 格式檔案, 轉入 Flotherm XT 後的 PCB 參數應該都自動設定完成

如果 PCB 不等向性熱傳導係數設定錯誤, 溫度結果應該會非常奇怪

您說的 AD 應該是 Altium Design 吧, 應該可以參考以下網頁說明 : www.altium.com/documentation/altium-designer/edaexporter-dlg-pscidfexportfrmfile-export-idf-ad?version=22&srsltid=AfmBOoqVWsAWrFIBgUmH5bQb19AUHgn4ePckobyuX8h8_8ZVFH-W7A11

@@errotg7973 這應該是有哪裡設定錯誤，正常情況的計算，瓦數會由小慢慢增加至您所設定的瓦數，然後最終達到熱平衡

@@_EFD_Corporation 請問網格建立順利進行，但是在計算時回報模型錯誤，是什麼方面的錯誤？檢查過了模型沒有破圖 交疊等問題，也給予了所有的環境參數了

網格有生成成功

@@errotg7973 若發熱源的網格不夠，也會出現錯誤訊息

Flotherm XT 無法生成網格的原因大部分是 3D CAD 圖檔有破圖, 建議先執行 Check Geometry 看看是否有錯誤訊息.

這的確是以質量守恆為依據, 因為這個題目的已知邊界條件為入水口流量及溫度, 所以用 Fix Flow 來設定 inlet, 可以直接輸入流量及溫度, 而 outlet 則輸入相同流量即可, 溫度是未知. 針對水冷系統, 的確也可以用 Flow device 來驅動流體, 但通常是針對 closed loop 的水冷循環系統, 因為 Flow device 無法設定入水溫度條件

My dout is transient Total time is 240 seconds sir Power One is 1.314 to 0-16 seconds Second power is 4.314 to 16-20sec Third power is 5.436 to 20-240sec MOSFET total 24 mounted on pcb Condition is 1secnd on and another 0.1sec is off What is amplitude How to create pluse What is raise time What is fall time Plz explain me sir

Actually iam asking this doubt sir since waiting for you last 15 days sir

You should be able to build TO247 by modify TO220, because TO247 is similar to TO220. And you can quick build TO220 model from Flotherm XT default library.

Real MOSFET material different library MOSFET material different sir Real MOSFET copper and plastic but library MOSFET material different sir both are not matching??

Default model in library is just for reference. Geometry and material maybe different with yours. If your model are using copper and plastic, you can setup real material in Flotherm XT.

Thank you for your information. But this is already a full transient simulation process.

Sir MOSFET on off 1 minute off 1 minute on total duration time 240 seconds please make one videos pluse' amplitude and powerlaw and other options do one video plz I am request you please language in English sir Chinese is not understanding sir plz sir

You mean pressure result inside the room? Positive or negative? If you want to know the pressure result inside the room. You can use Volume Region or Monitor point to get the data.

This is a good question. I think both Flotherm and Flotherm XT have particular advantages. For example, if you already have 3D CAD file, I think XT is more easy for you to build the model. Because you can import the 3D CAD file and setup material properties and mesh easily. But, if you don't have any CAD model (very early design stage), you can use Flotherm cuboid or SmartParts to build model easily. So, most of our customers are using Flotherm Flexx license. You can use "Flexx license" to open Flotherm OR Flotherm XT. Depend on what model you want to build.

​@@_EFD_Corporationah, ok. Thanks for the info.👍

I don’t understand. Please use English, thank you very much.

​@@_EFD_Corporation Hello, thank you for your reply. I ask for your help. Do you have links to written training articles on simcenter flovent? Everything I found on the Internet was of poor quality and contained little information

@@андрейпилипенко-л5ю You are right. There is no written training material on internet. That’s why we make this training video for our Flovent customers.

新版 FLOEFD 的 Physical feature 的確變成您寫的這樣, 只需要勾選 Conduction 就會考慮固體的熱傳導

@@_EFD_Corporation 了解了！ 感謝回覆！

原本的 PQ curve 會根據 Value 修正成 Derated PQ curve，並根據實際的系統阻抗求得Derating PQ curve 的操作點，也就是您需要的流量及靜壓值，謝謝！

您提到的這三個設定，影片裡面應該都有說明才對。

當您建構完成 Detail IC Model 後, 若要產生 2R model 時, Package Creator 會自動將 Detail IC model 轉入 Flotherm XT, 並自動建構兩種 JEDEC 測試環境 (Top Cold Plate for Rthjc / Ring Cold Plate for Rthjb) 並完成計算, 就可以取得 2R 的參數來輸出 2R model.

@@_EFD_Corporation 謝謝指教。 軟體是否嚴格按jedec 所要求，在板表面 離封裝1mm取到Tb 的溫度值? 另，自動計算所使用的pcb是否也是jedec 標準板？謝謝。

軟體的使用手冊說明是依照 JEDEC 規範來求得熱阻數據。當然您也可以自行建構標準 JEDEC 測試環境，包括 PCB 板，這兩種方式都是可以的。

@@_EFD_Corporation thanks a lot for your explanation 😄

Altium Designer 支援 ODB++ 格式檔案的輸出, 所以一樣可以透過 .tgz 檔案匯入. 您可以參考 Altium Designer 網頁 (www.altium.com/documentation/altium-designer/nfs-16-0support-for-zipping-odb-output-in-tgz-format-ad?version=16.0)
