finding geometrical entities with Abaqus / Python

[edumalta]

Good evening fellow colleagues,

I am working with abaqus python scripts and having a serious trouble with entities selecting. One particular example is selectig all the faces in a certain region where z=0.
I am using the "findat" function, but I only know how to specify a direct coordinate, not a range.

I tried something like:

faces2.append(f0.findAt(((all,all, 0.0), )))

That is so easy to do in ANSYS...

I would appreciate any help.

Thank you
