| Resumé≠ | The boundary element method (BEM) for geomechanics is a numerical approach that solves problems by discretizing only the boundary of the domain, using analytical solutions for the interior. Introduced by Brebbia in 1978 and refined for geotechnical applications by Crouch and Starfield, BEM is particularly effective for infinite or semi-infinite domains (underground excavations, foundations, rock masses) where finite element methods are impractical. | MODFLOW is the U.S. Geological Survey's open-source, modular finite-difference model for simulating three-dimensional groundwater flow through porous media. First released in 1984 and continuously updated — most recently as MODFLOW-6 — it is the global standard for quantitative hydrogeological analysis, widely used in civil engineering, environmental consulting, water-resource management, and groundwater contamination studies. |
