  Hello!
  I am a student and I am starting to work with Ansys for research purposes.
  I need to design a girder prestressed with cables. In the Static Structural module, I set the cable cross-sections to "Link/Truss", but when I click "Solve" I get an error. Can anyone help me solve this problem or help me get rid of this problem?

  The error shows your model is not fully constrained. You can use modal analysis to check which part is not fully constrained.

  Hi
  See these discussions (your beams are probably not sharing common nodes so they are not connected).

  Is it possible to prestress the structure with the Link/Truss option?
