Abstract
The ordering of a nematic liquid crystal in the presence of a smooth s urface is analyzed in detail. In particular, the force constants for h omeotropic anchoring are estimated by a local density functional metho d with data from molecular dynamics simulations. The system studied is a model Gay-Berne nematic liquid crystal. For the molecule-surface in teraction both an anisotropic and an isotropic one-particle potential are taken. In both cases a surface-induced smectic A phase is being ob served even though the phase is unstable in the bulk.
