NGIADP

Define a NGI-ADP material.

Parameters

name : str: String naming the material.
color : Color: Material appearance. color= rgb(129,114,132)
s_uA : float: Active undrained shear strength.
ratio_su_PA : float: Ratio of passive undrained shear strength over active undrained shear strength.
ratio_su_DSSA : float: Ratio of direct simple shear strength over active undrained shear strength.
gamma_dry : float: Dry unit weight in kN/m^3
gamma_sat : float: Saturated unit weight in kN/m^3
tension_cutoff : str: Apply tension cutoff. tension_cutoff = 'yes' or 'no'
sigma_t : float: Tensile cutoff stress, in kPa.
K0 : float: Earth pressure coefficient at rest.
hydraulic_conductivity_option : str: hydraulic_conductivity_option = 'isotropic' or 'anisotropic'
K : float: Hydraulic conductivity, in m/day.
Kx : float: Hydraulic conductivity in x, in m/day.
Ky : float: Hydraulic conductivity in y, in m/day.
Kz : float: Hydraulic conductivity in z, in m/day.
hydraulic_model : str: hydraulic_model = 'basic' or 'van_genuchten'
e : float: Void ratio.
alpha : float: Model parameter related to the air entry pressure.
n : float: Model parameter related to the rate at which water is extracted from the soil once the air entry pressure has been exceeded.
Sr : float: Residual degree of saturation (may be slightly greater than 0).
Ss : float: Fraction of water filled pores at full saturation (may be slightly less than 1).
reducible_strength : str: Apply reducible strength. reducible_strength = 'yes' or 'no'
