Many thanks for your prompt reply.
Yeah, I wish I had done may PhD in physical sciences now
Unfortunately, it seems that it is not the sleep threshould. I made it very small and finally set it to zero to test it. No effect.
Could it be that I somehow accidentally disabled gravity for the rope?
And finally: thank you so much for this great support form and your work here. That is really amazing!
Many thanks and best wishes,
Marie

Quote:In your case, chances are the solver's sleep threshold is keeping the rope asleep. The sleep threshold is a kinematic energy threshold (1/2 mv^2) so if the velocity of your rope is small, gravitational acceleration is small, the project's timestep is small, or the mass of the particles is small, the default threshold value will put them to sleep immediately.
