I need to compute the total kinetic energy for a polydisperse system in a 2D Couette flow as it is being sheared over time in order to determine whether the system has reached steady state conditions. I plan to plot the total kinetic energy versus number
of timesteps. Do I simply do this:
sumOver_i [ 0.5(mass_i x velMagnitude_i ^2) ]
velMagnitude_i = sqrt(vx_i^2 + vy_i^2)
For all particles i?
Or is there a simpler way?
