Abaqus UMAT Sand Hypoplasticity Model

[Isam.]

I am trying to implement a subroutine using UMAT for the Sand Hypoplastic model in Abaqus. I am beginner to Abaqus and I do not have experience with UMAT. I got the code from soilsmodels.com and it is attached here. There are many files and I do not know which one should be used or modified. Can someone please help me with implementing this model in Abaqus correctly.

Thank you in advance.

Start with Abaqus documentation examples - there you will find exemplary subroutines (including UMAT) and input files utilizing them. But you will have to configure a compiler for use with Abaqus subroutines first.
