## A simple example of data setting

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.
