I'm quite new with ansys, I was using Ansys AIM 17.2 and now I finally got the 19.1 version.

The problem is that now I don't know what is happening when I set up the electromagnetic simulation. In particular, I'm setting the current, before was sufficient to select the surface of the body where I'm applying the current but now something is different (see attached pictures). What am I doing wrong ?

Thanks for the help
