Pre-tension in a cable


Updated by Altair Forum User
Hello,
I am trying to model a beam supported by tension only cables. At the moment I use a CGAP element to model the cable but ideally I would like to add some pre-tension.
Does anyone know how to model pre-tension in tension only cable?
Thanks in advance.

Bolt pretension is possible in optistruct using 1d & 3d elements.But to simulate tension in Cable Rod element is also good.
Could you share snapshot of your model?

H Rahul,
Thanks for your reply.
The model is of a yacht mast.
Depending on load direction it is possible for some cables to go slack. Therefore, I am not sure that Rod elements are correct since they can take compression.

would be nice if you give a try with Rod elements.
Are you using Optistruct solver for analysis?
