*DECK NUMER3
SUBROUTINE NUMER3 (NCOUR,MULTC,NCODE,ZCODE,LX,LY,LZ,IORI,ISM,
1 POURCE,IMPX,NMBLK,IFR,ALB,SUR,NMERGE,INUM,MIX,DVX,NGEN,IGEN,
2 XX,YY,ZZ)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Surface renumbering algorithm for Cartesian geometry.
* The 3-D DP-1 approximation is not implemented.
*
*Copyright:
* Copyright (C) 2002 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/output
* NCOUR number of surfaces per block (input); number of out-currents
* per block (output).
* MULTC type of multicell approximation:
* =1 Roth; =2 Roth X ncour; =3 DP-0; =4 DP-1.
* NCODE type of boundary condition on each side of the domain:
* =0 not used; =1 VOID; =2 REFL;
* =3 DIAG; =4 TRAN; =5 SYME.
* ZCODE value of the albedo on each side of the domain.
* LX number of blocks along the X-axis.
* LY number of blocks along the Y-axis.
* LZ number of blocks along the Z-axis.
* IORI orientation of the blocks.
* ISM permutation index corresponding to each orientation
* (ISM(I,N)=I is the natural orientation).
* POURCE weight associated with each merged block.
* IMPX print flag (equal to 0 for no print).
* NMBLK total number of blocks in the domain.
* IFR index-number of in-currents.
* ALB transmission/albedo associated with each in-current.
* SUR surface associated with each in-current.
* NMERGE total number of merged cells for which specific values
* of the neutron flux and reactions rates are required.
* Many cells with different position in the domain can
* be merged before the neutron flux calculation if they
* own the same generating cell (NMERGE.le.NMBLK).
* INUM index-number of the merged cell associated to each cell.
* MIX index-number of out-currents.
* DVX weight associated with each out-current.
* Note: IFR, ALB, MIX and DVX contains information to rebuild
* the geometrical 'A' matrix.
* NGEN total number of generating blocks in the cartesian domain.
* IGEN index-number of the generating block associated with each
* merged block.
* XX X-thickness of the generating blocks.
* YY Y-thickness of the generating blocks.
* ZZ Z-thickness of the generating blocks.
