请教高手关于Computations with FieldOutput objects

from odbAccess import *
odb = openOdb(path='fieldOperation.odb')

# Get fields from output database.

field1 = odb.steps['LC1'].frames[1].fieldOutputs['U']
field2 = odb.steps['LC2'].frames[1].fieldOutputs['U']

# Compute difference between fields.

deltaDisp = field2 - field1

# Save new field.

newStep = odb.Step(name='user',
     description='user defined results', domain= TIME, timePeriod=0)
newFrame = newStep.Frame(incrementNumber=0, frameValue=0.0)
newField = newFrame.FieldOutput(name='U',
    description='delta displacements', type=VECTOR)
newField.addData(field=deltaDisp)

odb.save()

对于保存为一个新的odb，而且把所有的frame都保存下来，请问高手下面括号里面的内容，如(name='user',
description='user defined results', domain= TIME, timePeriod=0)；(incrementNumber=0, frameValue=0.0)；(name='U',description='delta displacements', type=VECTOR)
应该怎么填？
