[lammps-users] fix wall/reflect/stochastic diffusive vel?


In fix wall/reflect/stochastic diffusive what does the velx, vely, and velz do? From the manuel:

For rstyle diffusive, particles are reflected diffusively. Their velocity distribution corresponds to an equilibrium distribution of particles at the wall temperature.


So does the velx/vely/velz set the distribution broadness?


You best contact the contributing author of that particular fix (and perhaps also ask to have a clarification added to the manual ;-))
