Creating edge and node sets in Abaqus using Python

[gokul8707]

Hi guys

I have not much experience in Python scripting for Abaqus. I am importing an step file from catia to Abaqus. I want to create edge and node sets for applying boundary conditions. I came across an "findat" option to do it.. But i am not successful with it.

Is there any other option of selecting specific nodes at specific edges to form a set in abaqus?

assembly = mdb.models['Upper_Rail'].rootAssembly
assembly.Set(edges=assembly.instances['al_part'].edges.findAt(((308.044891, -747.636108, 669.81366),),), name='fixed_edge')
assembly.Set(name='fixed_nodes', nodes=assembly.sets['fixed_edge'].nodes)

The coordinates is the starting point of the edge which i need to select.
i get an error

Warning: findAt could not find a geometric entity at (308.044891, -747.636108, 669.81366)

Hi mate..
Is it possible to give a raw input to abaqus from python script.. I would like run my script having a raw input command to choose the material of the users choice. I am having a array of material values and i want abaqus to prompt whenever i run my script for materials
