how can we identify the node number of a particular result extracted in ansys.dpf.post (pyansys) in python?

[swatz3221]

I have extracted the elastic strain energy density at each node in python from an ansys .rst file using ansys dpf post (solution.misc.nodal_elastic_strain_energy_density) but dont know the information about the nodes at which the results are extracted. I think the results are extracted in a random node manner. So can anyone suggest me to get the results according to the node format that was given in ansys mechanical Or atleast know the node number at the result in python.

@swatz3221 , Once you load a given rst file with:

import ansys.dpf.post as post
sol = post.load_solution(r"c:\temp\file.rst")
res = sol.misc.nodal_reaction_force()

you can get the data at each field with : data = res.get_data_at_field(i) and their corresponding nodes ids with res.get_scoping_at_field(i)

you can also get the data with the fields container API:

fields = res.result_fields_container
#print(fields)
field = fields.get_field({"time":1})
#print(field)
field.data #return raw data
field.scoping.ids #returns the nodes or elements Ids
#or
ids = field.scoping.ids
for id in ids:
    field.get_entity_data_by_id(id)
