I am coding a coupled stress/PWP model with GeoStudio Add-in.

Does anyone know how to call the volumetric water content function and hydraulic conductivity function in the material function?

I ready coded Add-in VWC and Hydraulic conductivity functions. They work fine in SEEP/W. I want to integrate these functions into my Add-in constitutive model just as built-in coupled stress/PWP models.

it will be very appreciated for suggestions of any C# function that can solve my problem.
