Odd behaviour of guy-wires and no stress results
Odd behaviour of guy-wires and no stress results
(OP)
Hi,
I'm trying to do a structural analysis of a guyed tubular tower in ANSYS. The tubes are modelled using Pipe16 elements and the guy-wires are modelled using Link10 elements with the Long & perp motn and the Tension only options enabled.
I have tried to solve the problem using both large and small displacement analysis and only the small displacement analysis yields a converged solution. However, when I plot the deformations some of the guy-wires behave very odd (see attached picture) and no stress results exist.
Does anybody know why the guy-wires behave like this and why no stress results are written?
Thanks.

RE: Odd behaviour of guy-wires and no stress results
This could be caused by the link elements.
Try using 1 element in the cable. The link10 elements in this case are very flexible. Also use a initial strain in the link10 real. constant,this will also make you analyse more stable.
