Hi Garnet,
The software you mention in your post uses the limit equilibrium method. If you would like an approach without the limitations of limit equilibrium methods, please consider FLAC/Slope.
FLAC/Slope is a special, streamlined version of FLAC for evaluating the factor of safety (FoS) of soil and rock slopes in two dimensions with simple and fast model setup and analysis execution. FLAC/Slope can simulate stability problems under a wide variety of slope conditions, including: arbitrary slope geometries, multiple layers, pore pressure conditions, heterogeneous soil properties, surface loading, and structural reinforcement.
FLAC/Slope is now available for free. A fully functional version of FLAC/Slope can be download at: https://www.itascacg.com/contact-itasca/request-free-flacslope-software.
Best wishes with your project!
