Attached configuration

[sdast9]

This is really amazing work- thank you! I'm wondering if there is a way to maintain an attachment between 2 objects throughout the simulation. For example, in your initialize attached configuration example on the wiki, the objects fall together, but then separate after colliding with the ground. Is there a way for them to maintain the attachment (i.e. minimal distance between nodes) throughout the simulation?

Great question! The simulator currently does not directly support it. You could think about implementing extra equality constraints in C++ to the system such that the relative positions of certain pairs of nodes are fixed.

Agreed. I will have to learn C++ beyond "hello world" and study your code closely to get there. Just wanted to confirm that before taking on the challenge. Thanks again for this outstanding contribution!

Sure! I really appreciate your interest and acknowledgment!
