The summary result of a 3D solution with the detailed output window.

  • Possibility to use Digital Elevation Model (DEM) files to represent the ground surface or stratigraphic layers.
  • Checking for data errors.
  • Warnings for improperly specified sliding surfaces and other conditions.
  • Choice of Coulomb isotropic, Coulomb anisotropic or non-linear (Hoek and Brown, 1981) material strength models.
  • Discontinuities (joints) with distinct strength properties and piezometric conditions, which can be specified to form parts of the sliding surface.
