將Abaqus宏轉換為python腳本

[英]Transforming an Abaqus macro into a python script

 原文  2016-09-23 13:39:28  8   1    python/ macros/ abaqus

問題描述

我正在使用Abaqus（6.13）來運行FEM熱模擬。 我需要在該模型上獲得總的外部熱通量。 我的搜索表明，獲得它的唯一方法是在整個模型上求和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。

為了簡化我的導出，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數據的報告后結束。 這個生成的宏很大（~90萬行），所以我在這里給你一個裁剪版本：

OdbMacro1()

我在最后跟隨搜索結果添加了對OdbMacro1的調用。

我想從python文件中運行GUI外部的宏（或至少是有用的部分）。 當我這樣做時（使用“C：\\ Path \\ to \\ python \\ file \\ folder> abaqus python macro.py”），我收到一個錯誤： 

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

。 我不明白問題是什么。 我嘗試在文件的開頭添加“import odbAccess”，但是我得到了同樣的錯誤。 我想我應該在開頭添加一些代碼，但我無法繞過哪些代碼。 你可以幫幫我嗎？

順便說一句，它是次要的，但我覺得我可以簡化功能：

  • 在函數開頭的一堆導入中我不確定是否需要所有我可以刪除一些？
  • 在同一操作中對歷史輸出求和（或平均）的所有節點形成一組。 有沒有辦法使用它來避免在宏中使用每個單獨的歷史輸出？

感謝您的回答。 :)

這是一個基本上你想要的腳本:(你看我們只需要三個導入） 

from abaqus import *
from abaqusConstants import *
import visualization
odb=session.openOdb(name='/full/path/Job-1.odb')
session.viewports['Viewport: 1'].setValues(displayedObject=odb)
session.xyDataListFromField(odb=odb, outputPosition=NODAL,
          variable=(('NT11', NODAL),  ),
                   nodeSets=('PART-1-1.SETNAME', ))
keyname='From Field Data: NT11  at part instance PART-1-1'
# run this to see what the keys look like:
# [ o.description for o in session.xyDataObjects.values() ]
temp=[o for o in session.xyDataObjects.values() if
         o.description.find(keyname)==0]
#note if you only have requested one data type you could just do:
#temp=session.xyDataObjects.values()
session.writeXYReport(fileName='test.rpt', xyData=temp)
#alternate way to directly write data instead of using writexyreport:
f=open('test.dat','w')
for o in temp: f.write('%i %g\n'%
     (int(o.description.split()[-1]),o.data[-1][-1]))
f.close()

使用abaqus cae -noGUI script.py或abaqus cae noGUI=script.py
