Geometry

Height H Face slope (H:1V)

Toe bench Crest bench

The crest sits on the right and the mass slides to the left, which is the convention the solver uses internally.

Materials

Layers

Layers are listed from the top down. The first one starts at the ground surface; every layer below it needs a boundary.

Groundwater

Model

A pore-pressure ratio r_u can be set per material instead; it overrides the water table for that material.

Seismic k_h Seismic k_v

Include a tension crack

Depth Water fill (0–1)

Estimate the depth from the strength
