    Dear Naveen,
    Here is the model profile page
    https://soilmodels.com/hyposand/
    and in the download section you find two different umat implementations. Is this what you need? Or you have particular problem in Abaqus 6.13? In that case, someone using this Abaqus version would have to respond.

    Hello everybody,
    I’m trying to use hyposand in abaqus. i have some trouble.
    1- it seem’s the model is just usable for saturated sands. doesn’t it? i tried to model dry layers above to water table by putting Bulk_w as zero. but very large displacement at that layer occurred.
    2- is it possible to define initial pore pressure or it just developed for excess pore pressure calculation? if it’s possible, it’s should be defined in sdivini or in umat subroutine?
    3- is the vumat-umat interface that uploaded in the site compatible whit each umat in the site?
    with regards
    Mohamad
