I am trying to model a physical system by (lets say the system is a long deformable object, on which I can apply forces). It can be described by Cosserat Rod theory and discretized, by modelling it trough several spheres. If I now apply forces on one of the spheres, to me it seems, like the force reaches the other spheres far slower if I have many spheres. I am solving the positions based on a symplectic Euler scheme and using a constraint to keep the spheres at approximately the same distance from each other in order to account for deformation of my object. Through this constraints and the Euler scheme, the force gets transported. I am now wondering, if there is a theoretical expectation, how the time the force propagation takes, will evolve with the number of spheres for example. An idea, what theory could be used to describe this, would be very helpful, thanks!
