Dear colleagues,
I'm wondering if someone can tell me how is it doable to extract the exterior node labels of a meshed model through scripting?
Enclosed please find the corresponding model picture which I'm interested to do so.

Thank you in advance.

Maybe you can select the nodes in CAE before the analysis and create a nset.

But using a script in the odb, you know how the radius of the exterior nodes change with the Z coordinate and with this in mind you can select the exterior nodes using a script.
 
Thanks neslon for your response,

actually, I did exactly the same as you said by scripting. However, I was wondering if there is a more straightforward command for that!
It's a kind of ridiculous if there is no such method to extract the exterior nodes directly, isn't it? I remember Ansys enabled me to do so.
 
create a nodeset in CAE before the analysis.
otherwise you will need to lookup nodes that are common to only 4 elements (and not 8, if it's a full brick mesh)
