Number of nodes is 71,772,
Number of elements is 69,250,
but the number of 'S' or 'PEEQ' values in odb file is 277,008, it is 4 times of elements.
>>> len(odb.steps['step1'].frames[1].fieldOutputs['PEEQ'].values)
277,008
>>> prettyPrint(odb.steps['step1'].frames[1].fieldOutputs['PEEQ'].values[0])

nodeLabel show None, how do I know which one is the node?
Oceanus Lingose To obtain the node label of fieldOutputs in an Abaqus odb file, utilize the mesh attribute of the FieldOutput object. The mesh property returns a Mesh object that contains information about the mesh's nodes and elements.
Here's how you can use it to obtain the node label for each field output value:
odb = session.openOdb(path='example.odb')
step = odb.steps['step1']
frame = step.frames[1]
field_output = frame.fieldOutputs['PEEQ']
mesh = field_output.mesh
# Iterate over each field output value
for value in field_output.values:
# Get the element label and integration point index
element_label = value['elementLabel']
integration_point = value['integrationPoint']
# Get the corresponding element
element = mesh.getElementFromLabel(element_label)
# Get the node labels for the element
node_labels = element.connectivity
# Get the node label for the integration point
node_label = node_labels[integration_point-1]
# Do something with the node label
print(node_label)
This code will display the node label for each field output value that corresponds to the element's integration point with the specified element label.
To extract nodeLabel of fieldOutputs of S/PEEQ in an Abaqus odb file using a Python script, you can use the "odbAccess" module in Abaqus. The steps to extract the data are as follows:
Here is an example of how you can extract the node label of fieldOutputs of S/PEEQ in an Abaqus odb file using Python:
from odbAccess import *
# Open the odb file
odb = openOdb("your_odb_file.odb")
# Access the desired fieldOutputs of S/PEEQ
fieldOutputs = odb.steps["Step-1"].frames[-1].fieldOutputs["S/PEEQ"]
# Extract the node label
nodeLabels = [node.label for node in fieldOutputs.nodes]
# Close the odb file
odb.close()
# Print the node labels
print(nodeLabels)

Hi, Oceanus. Have you solved your problem? I have also met similar problem when try to extract PEEQ from a node.
