compute dpd command¶
Syntax¶
compute ID group-ID dpd
- ID, group-ID are documented in compute command
- dpd = style name of this compute command
Examples¶
compute 1 all dpd
Description¶
Define a computation that accumulates the total internal conductive energy (U_cond), the total internal mechanical energy (U_mech), the total internal energy (U) and the harmonic average of the internal temperature (dpdTheta) for the entire system of particles. See the compute dpd/atom command if you want per-particle internal energies and internal temperatures.
The system internal properties are computed according to the following relations:

where N is the number of particles in the system
Output info:
This compute calculates a global vector of length 5 (U_cond, U_mech, U, dpdTheta, N_particles), which can be accessed by indices 1-5. See this section for an overview of LAMMPS output options.
The vector values will be in energy and temperature units.
Restrictions¶
The compute dpd is only available if LAMMPS is built with the USER-DPD package and requires the atom_style dpd.
