  Within the framework of the local-equilibrium approach, the equilibrium and
nonequilibrium properties relevant to the hydrodynamics of the perfect
hard-sphere crystal are obtained with molecular dynamics simulations using the
Helfand moments associated with momentum and energy transports. Since this
crystal is face-centered cubic, the hydrodynamic properties we consider are the
hydrostatic pressure, the isothermal bulk modulus, the specific heat capacities
and their ratio, the three isothermal elastic constants
$(C_{11}^T,C_{12}^T,C_{44}^T)$, the heat conductivity, and the three
viscosities $(\eta_{11},\eta_{12},\eta_{44})$ (in Voigt's notations). These
properties are computed as a function of the particle density. The pressure and
the transport coefficients diverge near the close-packing density, as the
collision frequency per particle does.
