Hello

I intend to monitor the kinetic energy of a particular subset of balls within a larger group. However, when using the “ball.energy(‘energy-kinetic’)” command, it provides me with the total kinetic energy of all the balls. Is there a method to monitor the kinetic energy exclusively for a specific subset of balls?

Thank you

Hello @mehrdad,

To my knowledge the `ball.energy()`

FISH function only returns the total energy for all balls and there is not a function to specify which ball.

However, you can loop through the balls in a group to find the kinetic energy manually from the inertial mass, velocity, moment of inertia and angular velocity (spin).

Hello @dblanksma

Thank you for your response. Are you aware if the PFC 7 manual has the kinetic energy equation or not?
