(c) The segmentation of the F-array

Variables representing physical quantities of the same kind, for example all the current-time pressures for a "slab" of contiguous cells, are stored contiguously in segments of the F-array. The numbers of like variables in a segment (see the Fortran-coding entry for the meanings of the abbreviations) are:-

The FFV's other than WSV's each occupy a total of NZ segments, so that the total number of F-array locations is NX*NY*NZ; but these segments are separated by segments pertaining to other FFV's for the same slab.

It is the existence of this orderly arrangement which permits the LF of particular variables at particular cells to be easily determined. The next section explains how.
