SUBROUTINE TRIDFH (ISPLH,IPTRK,IDIM,LX,LZ,LL4,NUN,SIDE,ZZZ,ZZ,
1 KN,QFR,IQFR,VOL,MAT,IDL,NCODE,ICODE,ZCODE,IMPX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Numbering corresponding to a mesh centered finite difference
* discretization of a 3-D hexagonal geometry.
*
*Copyright:

* version 2.1 of the License, or (at your option) any later version
*
*Author(s): A. Benaboud
*
*Parameters: input
* IMPX print parameter.
* ISPLH type of mesh-splitting: =1 for complete hexagons; =2 for
* triangular mesh-splitting.
* IPTRK L_TRACK pointer to the tracking information.
* IDIM number of dimensions (2 or 3).
* LX number of hexagons.
* LZ number of axial planes.
* SIDE side of an hexagon.
* ZZZ Z-coordinates of the axial planes.
* NCODE type of boundary condition applied on each side (I=1: hbc):
* NCODE(I)=1: VOID; =2: REFL; =6: ALBE;
* =5: SYME; =7: ZERO.
* ICODE physical albedo index on each side of the domain.
* ZCODE albedo corresponding to boundary condition 'VOID' on each
* side (ZCODE(I)=0.0 by default).
* MAT mixture index assigned to each element.
*
*Parameters: output
* LL4 order of the system matrices.
* NUN number of unknowns per energy group.
* VOL volume of each element.
* KN element-ordered unknown list.
* QFR element-ordered boundary conditions.
* IQFR element-ordered physical albedo indices.
* IDL position of the average flux component associated with each
* volume.
* ZZ Z-sides of each hexagon.
