-----

__ Description:__

This function relies on a geometric series where the segment length, the cell number and the ratio are the paramaters. \\
Cell size is refined at the left tip of the segment.

__Namelist__

   &MESH_FUNCTION_DATA  Function_Name="GEOMETRIC_SERIE_1" ,
                        Number_of_Cells= 32   ,
                        Length= 1.0  ,
                        Cell_Ratio= 1.05d-00     Reverse_Ordering= .false. /
                     
__Cell size distribution :__

$L$ is the Length. \\
$q$ is the cell-size ratio (Cell_Ratio). \\
$N$ is the Number_of_Cells.\\
$h(l)$ is the cell size\\
$l$ is the cell index.\\

\begin{align*} 

h(l)&= L.\frac{q^{l-1}-q^l}{1-q^N}, l= 2,N\\

\end{align*}
