Granular temperature of particles

Submitted by vinaym on Wed, 04/26/2017 - 18:58

Hello all,

Is it possible to calculate granular temperature of particles? I see that command compute temp/sphere is phased out.

Thanks and regards,
Vinay

Sorry, thats not what I meant. I wanted granular temperature as a measure of the velocity fluctuations in a granular system.

Thank you.

If you are modeling a gas, you could incorporate your equations directly into the input file via the variable command...
Something along the lines as
variable my_temp atom "(2.0/3.0) * (1.0/k) * (1.0/2.0 * mass * (vx*vx + vy*vy + vz*vz))"
This would give you temperature as a function of velocity for each atom.
