Topic: How to model unbonded external cables

Hi all ,  smile

I have sent a post before and you didn't answer me ,, please i need an answer

Please i want to model unbonded external cables but i can't ... the main problem is the slippage of cable in deviator points .
My question is how can i overcome slipping of cable at the deviator points ,,, which are the points where the cable direction changes ?
I modeled the deviator as steel plate and the cable passes through it but it always gives me slippage ????
Also i gave the deviator very small coefficient of friction to neglect it's effect on the cable
Is this a reason for slippage of the cable at deviator points ?
