Hello Soumya,
I understand that the issue is that the cable loses contact with the pulley/redirection point in Simscape Multibody when it straightens, which causes the simulation to fail.
As a workaround, you can try these approaches:
- Explicit-force redirect (simpler and robust): Treat the hole as a fixed point, compute tension and unit direction vectors for the two cable segments in Simulink, and apply equal-and-opposite forces using External Force and Torque blocks. This avoids contact loss and works even when the cable is straight. (https://www.mathworks.com/help/sm/ref/externalforceandtorque.html)
- Dynamic guide with segments (more physical but heavier): Model the hole as a small rigid guide (revolute/point-on-curve constraint) and represent the cable with short rigid segments linked by joints and light spring-dampers.
Hope this solves your query!
