SISIM: Sisim is a graphical user interface (GUI) for sisim3d an indicator kriging and conditional stochastic simulation program for discrete data (non-continuous data: e.g. clay, sand, gravel) developed at Stanford University by Gómez-Hernández and Srivastava (ISIM3D, 1990) and modified at the Colorado School of Mines by McKenna (1994) to utilize soft data. Up to eight indicators can be modeled in a single simulation. In its basic form sisim3d can be awkward to use, particularly when many simulations are required based on varying semivariogram models. This interface assists the user in handling data files, input parameters, coordinating multiple simulation, tasking jobs to other computers, calculating simulation statistics, and visualizing results.

The main interface is a simple menu driven GUI. Click for full size image

After a model has been run, the results can be displayed using aby of UNCERT's other visualization tools. Click for full size image
Array can also be used to generate summary statistics for a series of simulations. Click for full size image
