将Abaqus宏转换为python脚本

[英]Transforming an Abaqus macro into a python script

 原文  2016-09-23 13:39:28  6   1    python/ macros/ abaqus

问题描述

我正在使用Abaqus（6.13）来运行FEM热模拟。 我需要在该模型上获得总的外部热通量。 我的搜索表明，获得它的唯一方法是在整个模型上求和RFLE历史输出并且它工作正常。 问题是我有一个~300 000个元素模型，而Report / XY窗口的简单打开需要几个小时。

为了简化我的导出，我使用Abaqus的宏管理器创建了一个导出宏。 记录在abaqus中导入odb之前开始，并在导出包含X / Y数据的报告后结束。 这个生成的宏很大（~90万行），所以我在这里给你一个裁剪版本： 

# -*- coding: mbcs -*-

OdbMacro1()

我在最后跟随搜索结果添加了对OdbMacro1的调用。

我想从python文件中运行GUI外部的宏（或至少是有用的部分）。 当我这样做时（使用“C：\\ Path \\ to \\ python \\ file \\ folder> abaqus python macro.py”），我收到一个错误： 

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

。 我不明白问题是什么。 我尝试在文件的开头添加“import odbAccess”，但是我得到了同样的错误。 我想我应该在开头添加一些代码，但我无法绕过哪些代码。 你可以帮帮我吗？

顺便说一句，它是次要的，但我觉得我可以简化功能：

  • 在函数开头的一堆导入中我不确定是否需要所有我可以删除一些？
  • 在同一操作中对历史输出求和（或平均）的所有节点形成一组。 有没有办法使用它来避免在宏中使用每个单独的历史输出？

感谢您的回答。 :)

这是一个基本上你想要的脚本:(你看我们只需要三个导入） 

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
