XY index (2.4.1.5.)
Level/Volume breakpoints allow you to define a complex vessel shape as a series of segments.
A value is assigned to each level breakpoint and a corresponding value is assigned to each
volume breakpoint.
Volume values are defined in volume units and can be percent or volumetric; level values are
defined in level units, and can be percent or linear.
Level values
Range: 0.0000 to 999999 (m, cm, mm, ft, in, %)
Default: 0.0
Volume values
Range: 0.0000 to 999999 (% or volumetric units)
Default: 0.0
Enter up to 32 level breakpoints, where the corresponding volume is known. The values
corresponding to 100% and 0% levels must be entered. The breakpoints can be ordered from
top to bottom, or the reverse.
