FLAC3D Modeling • Introduction

Fields of Application

FLAC3D was developed primarily for geotechnical engineering applications. [CS: ??? what to do, what to do…] contains a bibliography of publications on the application of |flac3d| to geotechnical problems in the fields of mining, underground engineering, rock mechanics and research.

Some possible applications of FLAC3D are noted below. Because FLAC3D now has essentially the same capabilities as FLAC, many of the FLAC applications can now be extended into three dimensions with FLAC3D.
