Create assembly level element set

[Settler]

Hello all,

I've been trying to create an assembly level element set in Python. The closest I've been to it is with the following code.

mdb.models[Modelname].rootAssembly.Set(elements=mdb.models[Modelname].rootAssembly.instances['Rubber-1'].elements.getFromLabel(('Rubber-1',(12)), ('Rubber-1',(23)),),name='neop')

However, I get the error that "TypeError: arg1; found tuple, expecting int"

Any idea of how to create the set named "neop" with those two elements?

Thanks

This is how much closer I got to having it done, still getting error. Different this time. -> "Feature creation failed."

mdb.models[Modelname].rootAssembly.Set(name='Neop', elements=(mdb.models[Modelname].rootAssembly.instances['Rubber-1'].elements[12],))
