Still the industry standard for 2D limit equilibrium slope stability. The 2021 release streamlines modeling for complex stratigraphy and groundwater conditions.
Create a material library. Input unit weight, cohesion (c), friction angle (φ), and pore pressure coefficients (Ru or B-bar). For advanced users, define anisotropic strength or Hoek-Brown parameters for rock masses. rocscience slide 70 full 2021
