# Working Model 4D: Sliding down a rope

## Working Model 4D: Sliding down a rope

(OP)
I'm using Version 7.1 of MSC.Visual Desktop (Working Model 4D), and I'm trying to model an oblect as it slides down a rope.  The rop is terminated at two high points, and has a sag.  The object starts from one of the high points, and slides down along the rope's length.

Oh, and the rope's length increases (it is being payed out), with the force on the rope defined as such:

F_rope = K * (V_rope)^2

Eventually, the object touches the ground, and the simultation stops.

Problem1: A rope is a constraint!  You cannot slide along a constraint!

Problem2: How would one model a curved slot to act as if it was this rope of mine...?

TIA

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
