Dear lammps experts,

I am going to compute a moving region temperature. Actually, the moving region is a particle like a ball. I need to calculate its temperature. So, please let me know which compute command omit the velocity of this region center of the mass in order to calculate the temperature of this region. I have applied this command:

compute temp_ball ball temp/partial 1 0 1

in fact, I have removed the Vy of this region. is it right?

Actually, when I plot the Vy-time diagram, this region temperature which is initially 300k, decreases upon moving in Y direction. So, please let me know whether I am doing right or not.

Yours Sincerely,

wrong! compute temp/partial does not do what you say you want to do.

there *is* a temperature that does *exactly* what you ask for. check

out the documentation.

Thank you for your guidance. I finally found it in compute temp/com command.
