&MESH_FUNCTION_DATA Function_Name="TANH_TWO_SIDES" , Number_of_Cells= 32 , Length= 1.0 , Left_Cell_Size= 2.0d-02 , Right_Cell_Size= 3.0d-02 , Reverse_Ordering= .false. /
Cell size distribution h(l) :
\begin{align*} x(1)&= 0 \\ F(l)&=\frac{1}{2}(1 + \tanh( \alpha(\frac{l-1}{N})-\frac{1}{2})/\tanh(\frac{1}{2}) \alpha), 2 \leq l \leq N+1\\ x(l)&= L \cdot (\frac{F(l)}{\alpha + (1- \alpha) F(l)})\\ x(N+1)&= L \\ h(l)= x(l+1-x(l)\\ \end{align*}
$L=\text{Length}$
$N=\text{Number_of_Cells}$
$\alpha$ is a function of $\text{Left_Cell_Size}$ and $\text{Right_Cell_Size}$.
