Axi-Symmetric model

Axel_A

Hi,

I have multiple questions regarding axi-symmetric model:

• Do I need to adapt my PLOADX1 pressure (1bar) when I'm using an axi-symmetric model? To be sure it's 1bar for all the circumference.
• How do I define the symmetric axis of the shell for the analysis?
• Do Optistruc used X revolution axis by default? And do it used then always the center point coordinate Y and Z = 0 ?
• In Hyperview I can used the Symmetry (transform option), for X and Z axis, but how do I know the one used by the analysis?

Thx a lot!

Regards,

Axel
