    If "my_NS" refers to the named selection:

    my_NS.Location.Ids

    will return a list of the Ids of the entities scoped in the Named Selection. For a nodal named selection, these "ACT ids" are equal to the "APDL/mesh ids".

    Hi! I need your help. Why my named selection is empty? I created several named selections in Workbench. And I try to read the 'file.rst' to obtain the named selections to do further calculations. But it prints nothing. It seems that the named selections are not stored in the 'file.rst' file. Please help me! Thank you very much! The following is the code snippet.

    file = 'file.rst'

    model = dpf.Model(file)

    print(model.metadata.available_named_selections)

    Hi @tf90 , please open a separate post for this, as this initial post is about Mechanical automation API and on your side the issue is related to Mechanical DPF.
