Changing BEAM188 Line Bodies into LINK180 Elements
Multiple line bodies cannot have multiple end releases at a shared vertex. To treat the ends of beams as released in all rotations at a shared vertex when those beams are in a single line body, converting the BEAM188 elements of the line body into LINK180 elements can provide a workaround.
LINK180 elements have only UX, UY and UZ degrees of freedom, and at their nodes, act as if joints are spherical.
