Data lines for TYPE=ENRICHMENT: 

First line:

1、Element number or element set label.

2 、Relative position of the node forming the element connectivity.

3、Name of the enriched feature specified on the *ENRICHMENT option.

4、Value of first signed distance function.

5、Value of second signed distance function. Leave this entry blank if only the first signed distance function is needed.

Repeat this data line as often as necessary to define initial signed distance functions in various elements or element sets. The signed distance functions must be defined at all nodes within an element.
