Class HardSphereFluid

java.lang.Object

etomica.statmech.HardSphereFluid

public class HardSphereFluid
extends java.lang.Object

Computes EOS for HS fluid. Uses exponential of a polynomial with low order terms take from virial coefficients and high order terms fit to simulation data. The fitted terms take a different form that allows them to more efficiently describe the high-density behavior.

zFluid

public static double zFluid(double rho)

Asolid

public static double Asolid(double rho)

Returns the difference between absolute free energies between the given densities for solid (FCC) hard spheres. The result is computed using numeric integration with n points.
