*DECK FLPHFX
SUBROUTINE FLPHFX(NGRP,NEL,LX,LZ,MAT,VOL,FLUX,FXYZ,RATIO,VTOT,
1 IMPX,LFLX,LRAT)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Compute the flux distributions and ratios over the whole reactor core;
* print the normalized fluxes on files.
*
*Copyright:
* Copyright (C) 2007 Ecole Polytechnique de Montreal.
*
*Author(s):
* D. Sekki
*
*Update(s):
* V. Descotes 5/06/2010
*
*Parameters: input
* NGRP total number of energy groups.
* NEL total number of finite elements.
* LX number of hexagons.
* LZ number of elements along z-axis.
* MAT index-number of mixture assigned to each volume.
* VOL element-ordered mesh-splitted volumes.
* FLUX normalized fluxes associated with each volume.
* IMPX screen printing index (=0 for no print).
* LFLX fluxes printing flag: =.true. print on files.
* LRAT ratios printing flag: =.true. print on files.
*
*Parameters: output
* FXYZ mesh-ordered fluxes.
* RATIO fluxes ratios with respect to thermal fluxes.
* VTOT total reactor-core volume.
