Annealing with rigid body

Dear sir,

   I would like to model a homo-tetrameric protein. First, I would like to
find an appropriate arrangement of four identical rigid helix bundles by
performing simulated annealing protocol. Does anyone know how to keep fix
the conformation of helices during simulated annealing? Do I have to impose
the artificial constraints to keep the geometry or are there any other
ways to do it?
   Any comments are appreciate. Thank you.
