+__ 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.

+$L$ 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(1)&= 0 \\
-dh(l)&= \frac{q^{l-1}-q^l}{1-q^N}\\
+h(l)&= L.\frac{q^{l-1}-q^l}{1-q^N}, l= 2,N\\
-h(l+1)&= h(l) + dh(l)
