*DECK TRIASN
SUBROUTINE TRIASN(HNAMT,IPTRK,IPSYS,IMPX,NBMIX,NEL,NAN,NALBP,IPR,
1 MAT,VOL,GAMMA,SIGT,SIGTI)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Assembly of a single-group system matrix with leakage and removal
* cross sections for the simplified PN method.
*
*Copyright:
* Copyright (C) 2005 Ecole Polytechnique de Montreal
* This library is free software; you can redistribute it and/or
* modify it under the terms of the GNU Lesser General Public
* License as published by the Free Software Foundation; either
* version 2.1 of the License, or (at your option) any later version
*
*Author(s): A. Hebert
*
*Parameters: input
* HNAMT name of the matrix.
* IPTRK L_TRACK pointer to the TRIVAC tracking information.
* IPSYS L_SYSTEM pointer to system matrices.
* IMPX print parameter (equal to zero for no print).
* NBMIX number of mixtures.
* NEL total number of finite elements.
* NAN number of Legendre orders for the cross sections.
* NALBP number of physical albedos.
* IPR type of assembly:
* =0: calculation of the system matrices;
* =1: calculation of the derivative of these matrices;
* =2: calculation of the first variation of these matrices;
* =3: identical to IPR=2, but these variation are added to
* unperturbed system matrices.
* MAT index-number of the mixture type assigned to each volume.
* GAMMA physical albedo functions.
* VOL volumes.
* SIGT total minus self-scattering macroscopic cross sections.
* SIGT(:,NAN) generally contains the total cross section only.
* If IPR.gt.0, SIGT contains perturbed or derivative values.
* SIGTI inverse macroscopic cross sections ordered by mixture.
* SIGTI(:,NAN) generally contains the inverse total cross
* section only. If IPR.gt.0, SIGTI contains perturbed or
* derivative values.
