Hi all,

I’m running an Abaqus/Explicit 2024 model that needs two user subroutines:

Both files sit in the same working folder:

C:\\Users\\amrithma\\Documents\\Abaqus_simulations\\HSLA_100_steel\\velocity_2220\\Trail_1\\Fortran files
│  entropy_vumatht.f
│  TSI_VUSDFLD.f
│  Trail12220.inp  …

I tried to build a user library with:

abaqus make job=MyHVIProgram user="entropy_vumatht.f TSI_VUSDFLD.f"

but Abaqus returns

Abaqus Error: The following file(s) could not be located:
entropy_vumatht.f TSI_VUSDFLD.f

Launching directly with abaqus job=Trail12220 user=… gives the same “file not found” message.

Setup

• Windows 10 ×64
• Visual Studio 2022 + Intel Fortran (oneAPI 2024)
• Abaqus command prompt (vcvars / ifort paths are active)
• First time using user subroutines

What I’m after

1. The correct abaqus make / linking workflow to bundle both *.f files into a single DLL (or a set of “uniquelibs”) that Abaqus/Explicit will load.
2. Minimal example commands or batch script that work with VS 2022.
3. Any abaqus_v6.env edits I should make (usub_lib_dir, uniquelibs, etc.).
4. Common pitfalls when mixing VUMATHT and VUSDFLD (precision, file names, order, …).

Any guidance or sample commands would be greatly appreciated—thanks!
