[Description:]
This fix differs from the command fix wall/reflect which is equivalent
to the mirror reflection in that the post collision velocity of the atoms
in the stochastic wall is random. The randomness can come from many sources:
thermal motion of solid atoms, the surface roughness, etc... Three
stochastic wall models are implemented.
This fix models the stochastic and inelastic collisions between fluid atoms and a solid boundary. The solid surface with finite temperature and moving speed can exchange energy with the fluid atoms. Different from the command fix wall/reflect which is equivalent to the mirror reflection, the post collision velocity of the fluid atoms in the stochastic wall model is random. The randomness can come from many sources: thermal motion of solid atoms, the surface roughness, etc... Three stochastic wall models are implemented.

reflected diffusively. Their velocity distribution corresponds to the
