Getting the body ID from a node ID in Mechanical scripting

Just wanted to share a quick snippet that allows one to get the body ID (and potentially select the body and get information about the body) from a node ID using Mechanical scripting:

Get_body_by_node.py

Happy scripting!

Code in attachement:

my_node = meshData.NodeById( node_ID )
Find out which body the node belongs to
body_ID = my_node.BodyIds[0]

body = DataModel.GetObjectById( body_ID )

Hi @Pernelle Marone-Hitz
Hope you've been well.
Is this only available in 2023 version?
when I attempted to use the BodyIds attribute in Ansys 2022r2, i get an error message saying: 'Node' object has no attribute 'BodyIds'.
I defined the mash as follows:

analysis = ExtAPI.DataModel.Project.Model.Analyses[0]
dataSource = dpf.DataSources(analysis.ResultFileName)
model=dpf.Model(dataSource)
mesh=model.Mesh

Node was defined as so:

node=mesh.NodeById(23742)

and here's the prompt:

node.BodyIds[0]

'Node' object has no attribute 'BodyIds'

Just checking to see if I've missed a step.
Is there another way to achieve this?

Kev

My appologies, just found your other post on this and saw my mistake.
mesh needs to be defined like this:
ExtAPI.DataModel.Project.Model.Analyses[0].MeshData

Thanks for this useful post Pernelle.
Cheers
