Request to obtain the sourse code of Figure 6 "The elastic rod under torsion..." in the article "Direct positon-based solver for stiff rods.

Could you please to upload the code of example KNOT in figure 6 in the rticle "Direct positon-based solver for stiff rods". Thanks very much!

This example was set up in an old framework which we do not maintain anymore. Unfortunately, nobody had time so far to implement the collisision detection for rods in the PBD framework.

hi janbender
Could you share this old framework or the rod collision part for us , very grateful!
Best,
Gang

Hi, thanks for you reply! In the simulation of rope contact, the penetration phenomenon will occur. The time step is adjusted to 0.001, and the contact mode of addCollisionCylinder is used. How to deal with this phenomenon? Please help with your suggestions.

I assume that the two adjacent collision cylinders will report a contact which is then resolved. In our simulation in the paper we deactivated the collision detection for neighboring cylinder elements. However, at the moment there is no functionality in the PBD library to handle this but I think this should not be hard to implement.
