  To model a nematic emulsion consisting of a surfactant-coated water droplet
dispersed in a nematic host, we performed a molecular dynamics simulation of a
droplet immersed in a system of 2048 Gay-Berne ellipsoids in a nematic phase.
Strong radial anchoring at the surface of the droplet induced a Saturn ring
defect configuration, consistent with theoretical predictions for very small
droplets. A surface ring configuration was observed for lower radial anchoring
strengths, and a pair of point defects was found near the poles of the droplet
for tangential anchoring. We also simulated the falling ball experiment and
measured the drag force anisotropy, in the presence of strong radial anchoring
as well as zero anchoring strength.
