internal constraints between two bodies

[giuma]

Bye to all,
I'm using ansys 12 for my thesis work and I'm at first arms; I have to insert some hinge-type bonds between two model bodies that I'm studying but I don't know how to do; I have seen on the help that to simulate external constraints (incaster type at the base) you can assign a null shift in all directions (preprocsolution>define loads>apply>structural>displacement.) but I don't understand how internal constraints are managed by the program.
Can you give me some suggestions?

Thank you.

Thanks, as for the type of bond, can one-sided constraints be inserted?
for example I want to insert a link on the long shift x that allows only ux+ and blocks instead ux-

I don't know, there's probably a command that sends you to a non-linear solution.
you may use contact or similar items (Always see the help and examples)

I still have a doubt.. in reality with the commands ce, cerig impose relations between 2 knots, there is no command that does the same thing but between two surfaces?
