  hi guys, i want to do 2-way -coupling system (using transient structural- fluent)
  
  in the input there's a pressure that increase little by little and attend 400000 pa
  
  in reality it's supposed , that the fluid pushs the piston (whish have a stifness and a preload)
  
  so i put layering method , and system coupling in output of fluid (which i define as a wall)
  
  should i active 1dof to make wall able to translate ?
  
  i need help please !
