Abaqus Python: Get Nodelabels of DisplayGroup

Hi SLC,

I want to get node labels from a display group with abaqus python (ODB).

I tried the following python code:
a=session.displayGroups['test']
vp.odbDisplay.setValues(visibleDisplayGroups=(a,))
k=vp.odbDisplay.displayGroupInstances['test']
k.nodes()

output: {'PART-1-1': (20,)}

But I don't want to change the displayed objects in the viewport.
But if I don't set "test" as visibleDisplayGroups I can't use displayGroupInstances and therefore I can't use the method .nodes().

I also tried:
session.displayGroups['test'].root.leaf.nodePick

Output: (('PART-1-1', 1, ('[#80000 ]',)),)


But I need the node labels (like .nodes()).

I tried more ways. But nothing was really exactly that what I wanted.

Are there any other ways to get NodeLabels from Displaygroup without changing the displayed Objects in the Viewport?

The actual goal is to get the fieldoutput of RF/CF from all nodes in the displaygroup and create a dictionary out of it.

Thank you very much.

Best Regards.
