FLAC3D and FLAC2D are numerical modeling codes for advanced geotechnical analysis of soil, rock, and structural support in three and two dimensions. FLAC3D and 2D are used in analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project where continuum analysis is necessary
3DEC is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. 3DEC simulates the response of discontinuous media (such as jointed rock) that is subject to either static or dynamic loading.
