"Data that specifies the soil work that results from the displacement of a retaining element. The displacement is defined using the rotation element r, which is assumed to be approximately equal to: f/H (wall top displacement / element height). The soil work mode can be determined as:

- Active pressure Ka -> ρa ≤ ρ < 0

- Static pressure Ko -> ρ = 0

- Passive pressure Kp -> 0 < ρ ≤ ρp"

so specify f/H as -0.406 or 0.406 or calculated f/H
