Description:

Symmetric function with an extremum.
Cell size is refined at left and right tips of the segment.

Namelist:

 &MESH_FUNCTION_DATA  Function_Name="GAUSS_LOBATTO"  , 
                   Number_of_Cells= 32   Length= 1.0                                                    
                   Reverse_Ordering= .false. /

Cell size distribution h(l) :

$L$ is the Length
$N$ is the Number_of_Cells
$x(l)$ is the coordinate.
$h(l)$ is the cell size.

\begin{align*} x(l)&=\frac{1}{2}L(1 - \cos(\frac{l-1 \cdot \pi}{N})), 1 \leq l \leq N+1\\ h(l)&= x(l+1)-x(l) \end{align*}

$l$ is the cell index.
