Structural Analysis Using Link as Model type with Line Bodies

      Hello Everyone,


      I have attached the diagram of the model which I am trying to simulate in ANSYS Workbench 2020 R1 Student Version. I was successful in running the model with element type as Beam, but as per I know beam element gives us bending moment too while truss or link element carries only compression or tension, I went through some of previous discussions and found that some used universal joint while some used beam end method ( which I didnt understand) the one peter had uploaded I ran the same file in my ANSYS but it thrown a error stating that one of the node is required for beam end which I didnt understood, I have attached my archieve file.

      The problem with the model is the beams have all been welded together at the common vertices by Shared Topology set to Merge, so the revolute joints are irrelevant.


      There are three solutions to this problem.



      • Change the Beams to Links, mesh with 1 elements per line body and add Z=0 displacement BC to keep the endpoints in plane.

      • Use Beam End Release commands. You can search for information on how to do that on this site or in the ANSYS Help system.

      • Set Share Topology to None.


                  


      Now each beam is free to act as an independent link.


      The first method is the simplest if you don't need to include beam bending.


      Archive 2020 R1 attached.
