Dr. Masin
I have downloaded the most recent dll for Plaxis that includes the HypoPlastic model for Clays that you developed. I see two new parameters (Gvh0 and n), both are shown are dimensionless parameters. Are these parameters equal in magnitude to Ag and ng (that are no longer listed as user input)?
I could not find the definition of these new variables in any of the listed publications or in the Plaxis implementation manual.
Your assistance clarifying this matter would be greatly appreciated.
Thanks in advance.
Fernando

Dear Fernando, yes, Gvh0 and n are Ag and ng from the paper exactly. For anisotropic stiffness, you can set ratio alphaG, or keep it to 1 if you do not consider anisotropy, or even leave it as 0 and then it should be automatically initialized to 1. Regards David
