Transient analysis of cable under gravity
Transient analysis of cable under gravity
(OP)
Hi,
I'm working on a model of inclined cable, consisting of LINK 180 element in transient analysis under the effect of its own weight only. I added an imaginary damper to damp the oscillation to reduce numerical error. The model works correctly as long as the "TENSION ONLY" KEYOPT in LINK 180 isn't activated, once I activate "TENSION ONLY", the solution never converges.
The APDL code is attached Link
Thanks a lot for help!

NLGEOM is ON, and I tried this prestress effect and nothing changed. Do you have another suggestion?
Thanks a lot
