LINK180 elements do not have any rotational DOFs. It is a 'truss' element. It does not have any bending stiffness. If you only constrain one node, it can rotate/pivot about that point. Some ideas to consider: 1.Apply sufficient restraints to prevent rigid body rotation. 2.When meshing lines with link elements only use 1 element per edge. Without bending stiffness, multiple links in series may have stability issues. 3.If a series of link elements are required, you may need to apply an initial tension to provide stability.

Why does rigid body motion often occur with LINK180 elements?
