Force Chains with fix rigid

Submitted by andybond13 on Wed, 10/16/2013 - 21:09

Hello, has anyone successfully been able to calculate and visualize the force chains within a multi-sphere body?

I'm using the "hybrid granular molecular" atom style with a "fix rigid molecule" command, and am curious to see the force within the conglomerations/molecules and how that changes over time, i.e. with contacts.

I realize that in some sense, force is simply a function of distance and since the rigidly fixed spheres are at a constant distance to one another, the force is constant. However, there must be a force added to enforce the constraint, right? Can this be dumped & visualized?

Many thanks!
