7. UNUSUAL FEATURES OF THE PROGRAM
a) Four outer boundary conditions may be imposed - zero flux, zero current or constant current/flux at the upper and lower boundaries.
Boundaries must be fulfilled by the trial-functions.
b) Scattering down from any energy-group to any other is allowed.
c) There are several possibilities in KASY to:
. Separate distinct trial-functions out of a file which contains a series of precalculated two-dimensional functions.
. Make group-collapsing of precalculated trial-functions by means of group-flux addition.
. Orthonormalize the precalculated trial-functions to get a better convergence.
