Hi,
I am using LS-Dyna.
I have several node sets in my input file. See below a screenshot from LS-PrePost

However, when I print available named selections in pydpf-core I get nothing. I'm following this documentation: https://dpf.docs.pyansys.com/version/stable/examples/00-basic/09-results_over_space_subset.html
This is my code:
data_sources = dpf.DataSources()
data_sources.set_result_file_path(d3plot[0], "d3plot")
model = dpf.Model(data_sources)
print(model)
print("Named Selections: ", model.metadata.available_named_selections)
and this is the output:

Named Selections: []
You can see that the named selections are empty.
My goal is to extract the movement of a specific part. I have saved that part as a node set. If there are any other methods that would be great.
