  The density profiles and corresponding order parameters of the hard
ellipsoids confined between two hard walls and also in contact with a single
hard wall are studied using the density functional theory. The Hyper-Netted
Chain (HNC) approximation is used to write excess grand potential of the system
with respect to the bulk value. To simplify the calculations we use restricted
orientation model (ROM) for the orientation of ellipsoids to find the density
profiles and order parameters. Density functional theory shows that there is a
uniaxial-biaxial phase transition near a single hard wall and also between two
hard walls for a fluid consisting of uniaxial hard ellipsoidal particles with
finite elongation.
