Write fehm zone format files that list
the outside node list and the associated outside area list.
There are two files written:
is a node list for each of 6 possible external boundaries.
If keepatt is specified, then
6 node based attributes are added to the
with the names top, bottom, left_w, right_e, back_n, and front_s.
A node can occur in multiple zones. For instance, a node located on a top
corner of the mesh can be found in zones for top, front_s, and left_w.
1 = top = top = positive z direction (0,0,1)
2 = bottom = bottom = negative z direction (0,0,-1)
3 = left_w = left or west = negative x direction (-1,0,0)
4 = front_s = front or south = negative y direction (0,-1,0)
5 = right_e = right or east = positive x direction (1,0,0)
6 = back_n = back or north = positive y direction (0,1,0)
is a list of Voronoi area vectors (Ax_i,Ay_i,Az_i) associated with each
external node. It is written to match the node lists as written in the
outside.zone file. Along with each outside zone tag (such as top),
there is a sum of each vector for that zone.
For applications such as infiltration, the z component (each 3rd value)
would be used from the top zone list.

If the keyword keepatt_voronoi
specified, three node attributes (xn_varea,
zn_varea) representing the voronoi area are added.
If the keyword keepatt_median
specified, three node attributes (xn_marea, yn_marea,
zn_marea) representing the median area are added and the file name will
Note that the old version file name file_name_outside.area has area
vectors computed with the median strategy.
