ABAQUS Index numbering for the surface

[SM1994]

Hello
I am trying to use python script to generate new surface in order to apply pressure on it using script.
I use the:
session.journalOptions.replayGeometry
session.journalOptions.setValues(replayGeometry=INDEX)
to achieve the index number, but the problem is that I cannot understand the logic behind indexing numbers?

The problem that I have:
As can be seen in the attached image, I can measure the coordinates of one of the hole surface using but when I use
session.journalOptions.setValues(replayGeometry=COORDINATE)to return the coordinate of the side surface, it does not make any sense to measure.

Now I am trying to use INDEX method to achieve the INDEX of the side surface.

Can anyone help me to understand how ABAQUS set the surface index sequence?
Thanks

If you know approximately where the surface is, then you can use findAt() or getClosest() to get the surface.
Or you loop over each surface and check certain properties to find the surface you are looking for.
