  Hello, i'm doing an analysis of a prestressed beam, this prestressing is made with structural stell cable, the beam is a metal beam of the "I" profile type.
  
  I'm fiding some erros, i already tried to exchange the beams for cables in the gometry confifurations in definitions - modal type.
  
  Attached is the imagens with the erros, i wanted some help, thank you!

  Firstly switch on Large Deflections in Analysis setting under solver controls.
  
  For the next step, do a Modal analysis first to check the sufficiency of your BCs and contacts. If you see no zero-frequency mode then proceed to the static analysis.

  Did you do the modal analysis first and checked for rigid body modes?
  
  Why activate large deflection: because you are getting a warning for the same!
