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 within-ellipse 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).
