Abaqus CAE Python后处理提取每一帧最大等效应力

使用Python语言对Abaqus CAE后处理结果进行分析，并提取一个分析步中每一帧的最大等效应力，其中Python代码如下：

from abaqus import *
from abaqusConstants import *
from odbAccess import *
import visualization

myFile=open('DATA.txt','w')

print('********************************\n')
myFile.write('********************************\n')

myOdb=openOdb(path='viewer_tutorial.odb')
myStepValue=myOdb.steps.values()

for step in myStepValue:
    print('The current step is: %s.\n'%step.name)
    myFile.write('The current step is: %s.\n'%step.name)
    frameID=0
    for frame in step.frames:
        print('The current frame is: %d.\n'%frameID)
        myFile.write('The current frame is: %d.\n'%frameID)
        frameID=frameID+1
        stressValue=frame.fieldOutputs['S'].values
        maxMisesValue=0
        for misesValue in stressValue:
            if misesValue.mises>maxMisesValue:
                maxMisesValue=misesValue.mises
        print('The maximum mises value of the current frame in current step is: %10.6f\n'%maxMisesValue)
        myFile.write('The maximum mises value of the current frame in current step is: %10.6f\n'%maxMisesValue)

print('********************************\n')
myFile.write('********************************\n')
myFile.close()
