WebThis induces a velocity gradient which can be monitored with the :doc:`fix ave/chunk ` command. The fix tallies the cumulative momentum transfer that it performs. See the :doc:`fix viscosity ` command for details. The fourth method is based on the Green-Kubo (GK) formula which relates the ensemble average … Webviscosity = style name of this fix command. N = perform momentum exchange every N steps. vdim = x or y or z = which momentum component to exchange. pdim = x or y or z = direction of momentum transfer. Nbin = # of layers in pdim direction (must be even number) zero or more keyword/value pairs may be appended. keyword = swap or vtarget.
