post tension in Abaqus

Hello,

 Am working on post tension prestressed concrete with Abaqus,

1-  I would like to know where to find the "initial conditions option and prestress hold" in which module??

2- Rebar option: as per the Help, it is mentioned that i can define a rebar as individual element not as rebar layer in a shell/membrane element. but also couldn't be able to find how and in which module?

Any suggestions?

Wating for a quick feedback

thanks
