*DECK BIVSBH
SUBROUTINE BIVSBH (MAXEV,MAXKN,IMPX,ISPLH,LX,SIDE,LL4,IHEX,NCODE,
1 MAT,VOL,KN,QFR)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Numbering of an hexagonal 2-D geometry with or without triangular
* mesh-splitting.
*
*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
* MAXEV dimension for array IGAR:
* if ISPLH=1: number of hexagons;
* if ISPLH>1: (6*(ISPLH-1)**2)*LX where LX is the number of
* hexagons.
* MAXKN dimension for arrays KN and QFR.
* IMPX print parameter.
* ISPLH type of hexagonal mesh-splitting:
* =1: no mesh splitting (complete hexagons);
* =K: 6*(K-1)*(K-1) triangles per hexagon.
* LX number of hexagons.
* SIDE side of an hexagon.
* NCODE type of boundary condition applied on each side
* (i=1: X- i=2: X+ i=3: Y- i=4: Y+):
* NCODE(I)=1: VOID; NCODE(I)=2: REFL; NCODE(I)=5: SYME;
* NCODE(I)=7: ZERO.
* MAT mixture index assigned to each hexagon.
* IHEX type of hexagonal boundary condition.
*
*Parameters: output
* LL4 number of elements after mesh-splitting.
* VOL volume of each hexagon.
* KN element-ordered unknown list.
* QFR element-ordered external surfaces: =1.0 on external surfaces;
* =0.0 on internal surfaces.
