-   * The cell size is variable along the I-direction.  +  
-     * The I-line is split in two equal parts.  +
-     * The function "TANH_ONE_SIDE" is applied over each part, with a reverse distribution over the 2nd part. This way is useful to define a perfect symmetrical distribution in regard to the mid-plane. +
-   * The grid is regular along the J-direction +
