Hello Friends, Greetings. We all know that particle simulations are high dissipation systems. Lets say we have a cuboid container defined by 6 primitive planes oriented along X-Y-Z axes, filled with spherical particles to a certain height, gravity acting along Z. When this system is fluidized (that is, particles are set into motion),
1. How can we calculate energy that is being lost due to (a) collisions, (b) friction?
I'm tracking instantaneous net energy of the system using compute totRotKE all erotate/sphere and compute totLnrKE all ke.
