I am attempting to have a sail interact with a rope that is in front of it.
When the sail billows out, I want it to press against the rope and billow
around it. I have tried several sets of settings to no avail. The sail just
billows through the rope and does not form around it.
The sail is created with MechSim and is a 50x50 mesh. The rope is an Iso CSG
cylinder.
1. Could the spacing on the masses in the mesh affect this? If the spacing
on the masses prevents a sail mass from colliding with the rope?
2. What collision settings and methods should I be using to cause the mesh
sail to collide with the cylinder (rope)?
3. Would I be better off creating the rope with masses and connections? The
current rope is very taunt, but I will be using loose ropes int he future.
4. Should the sail and each rope be placed in its own group?
I am just looking for some general guide lines. I will do the work if
somebody can point me in the right direction. If somebody could give me a
hint, I would really appreciate the help.
Thanks,
Tim

First: wrong group, followup set.

Partly - only the masses are checked for collision with the environment
so the 'rope' has to be considerably thicker than the distance between
the masses in the sail.

Probably, having the rope as a 'line' and the sail as a 'patch' will
make them interact correctly if you turn on mass-face-collisions.

This would make collision tests much faster.
