FLUX
keyword to specify that the group integrated flux is to be drawn.
MGFLUX
keyword to specify that the group flux is to be drawn.
icond
array of increasing energy group limits that will be associated with each of the Ng condensed
groups. The final value of icond will automatically be set to ngroup while icond >ngroup will
be dropped from the condensation. The number of group condensation entry Ng must satisfy
Ng ≤ngroup where ngroup is the total number of groups on the flux data structure.
3.16 The SAD: module
The SAD: module is used to compute the generalized adjoint fluxes associated with homogenized and condensed cross-sections.[40–44] The input specifications for this module are presented in Table 68.

FLUNAM EDINAM := SAD: PIJNAM LIBNAM TRKNAM :: (descsad)
FLUNAM
character*12 name of the FLUXUNK data structure containing the generalized adjoint fluxes
solution.
EDINAM
character*12 name of the EDITION data structure where the homogenized and condensed
properties and the generalized adjoint sources will be stored.
PIJNAM
character*12 name of the
matrices (see Section 3.6).
LIBNAM
character*12 name of the MACROLIB or MICROLIB data structure that contains the macroscopic cross sections (see Sections 3.1 and 3.2).
TRKNAM
character*12 name of the TRACKING data structure (see Section 3.4).
(descsad)
structure containing the input data to this module (see Section 3.16.1).
ASMPIJ
data structure containing the group dependent system
