KW - Density functional theory, molecular structure, numerical discretization, orbital-free.
AB - <p style="text-align: justify;">We give here an overview of the orbital-free density functional
theory that is used for modeling atoms and molecules. We review
typical approximations to the kinetic energy, exchange-correlation
corrections to the kinetic and Hartree energies, and constructions
of the pseudopotentials. We discuss numerical discretizations for
the orbital-free methods and include several numerical results for
illustrations.</p>
