我正在使用Abaqus(6.13)來運行FEM熱模擬。我需要獲得該模型的總外部熱通量。我的搜索表明,獲得它的唯一方法是在整個模型中總結de RFLE歷史輸出,並且它工作正常。問題是我有一個〜300 000個元素模型,而Report/XY窗口的簡單打開需要幾個小時。將Abaqus宏轉換爲python腳本
爲了簡化我的導出,我使用Abaqus的宏管理器創建了一個導出宏。記錄在abaqus中導入odb之前開始,並在導出包含X/Y數據的報告之後結束。 這產生的宏觀大(〜900萬行),所以我給你在這裏它的修剪版本:

OdbMacro1()
我添加了調用OdbMacro1末,繼搜索結果我在這裏和那裏。
我想在python文件的GUI外部運行該宏(或至少是有用的部分)。當我這樣做(用 「C:\路徑\爲\ python的\文件\文件夾> ABAQUS蟒蛇macro.py」),我得到一個錯誤:
Traceback (most recent call last):
File "macro.py", line 3, in <module>
from abaqus import *
File "SMAPyaModules\SMAPyaAbqPy.m\src\abaqus.py", line 15, in <module>
ImportError: abaqus module may only be imported in the Abaqus kernel process
。我不明白問題是什麼。我試着在文件的開頭添加「import odbAccess」,但是我得到了同樣的錯誤。我想我應該在開始的時候添加一些代碼,但是我無法繞過它。你可以幫幫我嗎?
順便說一句,這是次要的,但我覺得我可以簡化功能:在函數的開始
- 其中一堆進口的我不 確保所有需要我可以刪除一些?
- 所有節點的歷史記錄 輸出在同一操作中求和(或平均)形成一個集合。 沒有辦法使用它來避免在宏中使用每個單獨的歷史記錄 輸出?
謝謝任何導致答案。 :)
看到這裏的http:// stackoverflow.com/a/28374118/1004168 – agentp
您的其他問題,是的,你可以刪除unnescesary進口。如果您需要使用nogui從命令行運行它,請確保在刪除您認爲不需要的導入時以此方式進行測試。 – agentp
謝謝你的答案。您發佈的鏈接確實回答了我的主要問題。我已經從另一個來源嘗試過這種方法,但我複製的代碼沒有工作(在「noGUI」之後缺少「=」)。 對於次要的,我想我會通過試用和錯誤的進口(現在我可以運行我的腳本),但你知道是否有一種方法來處理集而不是單個節點?這會減少宏的大小。 最後,如果您通過答案功能而不是評論回答,我可以將您的答案標記爲最佳答案(我認爲這是我唯一的帖子) –
