modeling of an elastic isotropic soil

[aaataha]

Hi,

I am trying to model an elastic isotropic soil and I am wondering about the appropriate material to be used.
for the ElasticIsotropic material:

nDMaterial ElasticIsotropic $matTag $E $v <$rho>

is the soil shear modulus implicitly defined in terms of E and v?

Yes, the material will compute shear modules G=E/(2(1+v))
