Constant tension in sliding cable

Hi everyone,
Is it possible and what would be the best way to model a cable that slides on a saddle ?

Hi Sébastien,
you could add a truss element of length equal to the radius of curvature at the point of contact between rope and saddle and support that truss element at the center of the circle of curvature. The try a geometric non-linear analysis.
If you are interested in small displacements only, then an inclined support which is perpendicular to the contact plane would be sufficient.
