iMOD User Manual version 5.2 (html)

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.
