How to get the average stress of all elements
from odbAccess import *

list_mises = []
for step in odb.steps.values():
for frame in step.frames :
sum=0
totalTime = 0
frameTime = frame.frameValue+totalTime
field=frame.fieldOutputs['S']
subField = field.getSubset(region=fixSet)
length= len(subField.values)
for val in subField.values :
sum = sum + val.mises
ave = sum / length
list_mises.append(ave)
print(list_mises[-1])
print('ok')
