This strength model uses the following equation for dealing with anisotropy in the soil strength:
c=ch(cosαi)2+cv(sinαi)2
φ=φh(cosαi)2+φv(sinαi)2
The subscripts stand for horizontal and vertical. The horizontal and vertical components are specified. Alpha (α) is the inclination of the slice base.
For the anisotropic analysis, insert two values (horizontal , vertical) of the parameter geotechnical separated by - ex: ch-cv for cohesion (100-120)
