7. UNUSUAL FEATURES OF THE PROGRAM
a) Three outer boundary conditions may be imposed - zero flux, zero current or constant current/flux.
b) Inner boundary conditions may be used for rod calculations.
c) Normal and adjoint eigenvalue problems, fixed source and criticality search problems are solved.
d) Scattering down from any group to any other is allowed.
e) Included is a perpturbation part for r-z geometry and a routine for calculating any reaction rates or densities.
f) Subsequent cases can be queued in one job step.
g) Automatic source interpolation within subsequent cases to reduce calculation time.
h) Time-eigenvalue calculation.
i) Calculation of dynamical neutron life time.
j) Calculation of beta-effective.
k) Included in DIXY-2 is a subroutine that prints out an input description if the program is started with only one input card, containing the character string 'DESCRIPTION', punched from card column 1 (apostrophes omitted).
l) DIXY-2 contains a plot facility.
m) Space-energy dependent fixed source problems.
n) Directionally dependent diffusion coefficients may be specified for streaming problems.
