 In the data file, each block of data is attributed to a direction (I,J or K).\\
 Each direction can be split in several parts (segments) on which a specific distribution law is applied in order to place the discrete nodes.\\
-Each distribution law is defined by means of namelists that are described at the end of this page. The available functions are (click on it for details):
+Each distribution law is defined by means of namelists that are described at the end of this page.
+For illustrating how that works, let consider a domain length $L$ (in an arbitrary direction) split in $2$ parts with lengths $L_1$ and $L_2$ respectively over which discrete points are distributed ($N_1=6$ for the first segment, $N_2=8$ for the second one).
