* NPQ number of SN directions in four octants (including zero-weight
* directions).
* NSCT maximum number of spherical harmonics moments of the flux.
* MAT material mixture index in each region.
* VOL volumes of each region.
* TOTAL macroscopic total cross sections.
* NCODE boundary condition indices.
* ZCODE albedos.
* QEXT Legendre components of the fixed source.
* LFIXUP flag to enable negative flux fixup.

* DE second direction cosines ($\\eta$).
* W weights.
* MRM quadrature index.
* MRMY quadrature index.
* DB diamond-scheme parameter.
* DA diamond-scheme parameter.
* MN moment-to-discrete matrix.
* DN discrete-to-moment matrix.
*
*Parameters: input/output
* FUNKNO Legendre components of the flux and boundary fluxes.
