Modal analysis

Hello everyone:
When I perform a modal analysis of the structure, the eigenvalue results of the first few orders of modalities appear negative, so does anyone know where the error is. There is no error in the gravity analysis.
Thank you!

Re: CatenaryCable element

Thank you very much for your help. I tried to apply the force to the nodes at the ende of the element, but this does not have any effect on the displacement of the whole cable structure.
