Dear lammps experts,
I am going to monitor the temperature of a projectile before and after collision to a surface. I have applied “compute temp/com command” in order to exclude velocity of center of mass from calculation of the temperature. However, an almost 150k drop in the target temperature when it starts to move which is not physically meaningful.
I have also used the compute compute temp/partial command . but the results is the same!
any help is highly appreciated

which means, that something in your simulation setup is not “physically meaningful”.
the compute will only report what it computes but will not change anything. so something else is making the change. GI-GO,

Thank you for the clarification. You are right. I should not turn of the thermostat until the collision time is over.
