 The grid data are recorded in the appropriate files that depend on the code previously selected:
     * For Chorus, maille_yyyyy.dat : data are recorded in binary format. "yyyyy" is the number of the associated subdomain.
     * For sunfluidh :
-      * For sequential computation, maillx.d, mailly.d, maillz.d (one file per direction): data are recorded in ASCII format and ordered in two colums, the first one is the cell-index, the second one is the coordinate of the upper face of the cell.Be careful, by default the first index starts at 2. The first coordinate is directly provided by the code.
