8.6IFF-FUNCTIONS


8.6.1IFFCROSSSECTION-Function

Use the IFFCROSSSECTION to find those points where flowlines from an IFF file intersect with a given GEN file. The points are saved in an IPF file.

FUNCTION=

IFFCROSSSECTION

IFFNAME

Specify the name for the IFF file to be used, e.g. IFFNAME=D:\DATA \FLOWLINES.IFF

GENNAME

Specify the name for the GEN file to be used, e.g. GENNAME=D:\DATA \CROSSSECTION.GEN
(only GEN-types polygon and line, not rectangle or circle)

IPFNAME

Specify the name for the IPF file to be created, e.g. IPFNAME=D:\DATA \INTERSECTIONS.IPF

This IPF file stores the following items with each point of intersection:

XINTER

X coordinate of the intersection

YINTER

Y coordinate of the intersection

ZINTER

Z coordinate of the intersection

PARTICLE_
NUMBER

ID number of the intersected flowline

ILAY-FROM

Model layer at the start point of the intersected flowline segment

ILAY-TO

Model layer at the end point of the intersected flowline segment

TIME-FROM

Age (years) of the particle at the start point of the intersected flowline segment

TIME-TO

Age (years) of the particle at the end point of the intersected flowline segment

Example

FUNCTION=IFFCROSSSECTION
IFFNAME=D:\DATA\FLOWLINES.IFF
GENNAME=D:\DATA\CROSSSECTION.GEN
IPFNAME=D:\DATA\INTERSECTIONS.IPF

Example of the function result: 3D plot of intersection points coloured by age.
