Hi all,

I'm trying to link Fortran subroutines with Abaqus 2021, and I'm stuck on an issue that doesn’t occur on other identical systems.

I followed these instructions: They work perfectly on two other PCs that have the same system configuration as mine

System Info (Same for all PCs):

• Windows 10/11
• Abaqus 2021
• Visual Studio 2022 (with Desktop development with C++ workload)
• Intel oneAPI HPC Toolkit & Base Toolkit (2025 version)

The Issue (Only on My PC):

When I run: abq2021 verify -user_std , I get the following error in the verification log: 'ifx' is not recognized as an internal or external command, operable program or batch file.
 

Additional Steps Taken:

• I also followed this guide step-by-step: 
  
  (Used it manually because the .pyc file is incompatible with Abaqus 2021's Python version.)

Question:

What could be preventing ifx from being recognized by Abaqus only on my machine, despite an identical setup?

Any suggestions or ideas are greatly appreciated. Thanks!
