VISIM should feel familiar to anyone who has used GSLIB, as it is based on GSLIB code.
A Matlab interface to VISIM is available through the mGstat toolbox. Documentation for using the Matlab interface can be found here.
VISIM is an acronym for Volume Integration SIMulation.
VISIM is the groups first attempt to merge features of geostatistics and linear inverse theory into one complete theory.
For geostatisticians :
VISIM allow sequential simulation conditioning to noisy linear volume averages measurements of the underground. (for example as in x-ray tomography).
Both sequential Gaussian simulation and direct sequential simulation with histogram reproduction are supported.
The work is a collaboration between Andre Journel, Albert Tarantola, Klaus Mosegaard, Thomas Mejer Hansen and Yongshe Liu.
