Hello everyone, I am a mechanical engineering student of the bari polytechnic. I recently started working on my thesis project where I have to design ansys aluminum titanium panel with only i stringer.
I put you here under the code until I got here:

/prep7
!---- geometric features of the panel


Tskin=0. 1
! ---- Geometric characteristics of stringers
hweb_s=3

Until this point there should be no mistakes, only that I have a doubt as the stringers should be along the x axis, while here I come along the z axis. what am I wrong?

I'm sure there's a mistake here because from a panel I find myself a cylinder, where am I wrong?

to understand the error paste one to one the commands in the toolbar to understand which both the command and from the panel (retangle) pulls out the cylinder
 
I don't know.
There are variables but I do not have the magic sphere to know what they refer to:)
 
Of course I checked! Frankly I have been very courteous and kind and I do not understand this hostility!
I checked and checked but I can't find a mistake!
