GSLIB Help Page: ELLIPSIM

Description:

This program provides a very simple example of Boolean simulation:
ellipsoids of various sizes and anisotropies are dropped at random until
a target proportion of points withinellipse is met. The ellipsoids are
allowed to overlap each other.

Parameters:

outfl: the simulated realizations are written to this file. The
output file will contain the unconditional simulated indicator values
(1 if in an ellipse, zero otherwise) cycling fastest on x
then y, then z, and then simulation by simulation.

nsim: the number of simulations to generate.

nx, xsiz: definition of the grid system (x axis).

ny, ysiz: definition of the grid system (y axis).

nz, zsiz: definition of the grid system (y axis).

seed: random number seed (a large odd integer).

targprop: the target proportion of ellipse volume.

For the different types of ellipsoids to be added:
radiusx, radiusy, radiusz, angle1, angle2, angle3, and
weight specify the ellipsoid size, orientation,
and relative proportion (counting).
