How to create curtain-like rope simulation in Omniverse issacSIm?

Hello!!

In one of the videos shown in this NVIDIA video (https://youtu.be/7ozs5EsvVGE)、
there is a scene where a group of strings (like a curtain) hangs down and drapes along a colliding object.
I attached a scene.

I have a few questions about how this is implemented:

- Is this simulation using Deformable Bodies?

- How are the strings modeled?

Are they individual string objects arranged side by side?

Or is each string composed of multiple small connected objects (segments), and then those strings are arranged side by side?

- Are there any hints, best practices, or recommended approaches for creating this kind of physical simulation?

Best Regards.
