Class MeterTensorVelocity

java.lang.Object

etomica.data.meter.MeterTensorVelocity

All Implemented Interfaces:

DataSourceAtomic, java.io.Serializable

public class MeterTensorVelocity
extends java.lang.Object
implements DataSourceAtomic, java.io.Serializable

A meter to compute the velocity component of the pressure tensor. Averages a tensor quantity formed from a dyad of the velocity of each atom. Specifically, the quantity averaged is 1/N * sum(pp/m), where p is the momentum, m is the mass, and the sum is over all N atoms.
