Description:
-
Truncate multiple Gaussian fields according to thresholds that
can vary locally.
-
Parameters:
-
gausfl: input data file with the Gaussian realizations that will
be truncated to create categorical variable realizations.
-
outfl: output data file for categorical variable realizations.
-
nsim: number of realizations
-
nx, ny, and nz: size of the simulation grid
-
ncat: number of categories
-
cat() and proportion(): the integer codes for each
category and its corresponding global proportion
-
pcurve: if set to 0 then there are no proportion curves and the
global proportions are used to establish the thresholds for
truncation. If set to 1, then proportion curve files are
considered for locally varying thresholds. ncat-1 proportion
files are needed:
-
propfl: file containing a regular 3-D grid (same size as the
input Gaussian realizations) containing the local proportions of the
ncat-1 categories.
-
icolprop: column with locally varying proportion
