Integrating Abaqus 2024 with Intel Fortran Compiler 2025 and Visual Studio 2022 for subroutine implementation (such as UMAT and VUMAT) can be tricky due to compatibility issues that arise with different versions of compilers, IDEs, and Abaqus itself. Here’s a guide based on common setups and known configurations to ensure compatibility between these tools:

1. Installation Order: Abaqus 2024: Start by installing Abaqus 2024 as the first step. This should also install necessary dependencies, such as the default compilers and environment setup. Intel Fortran Compiler 2025: Next, install the Intel Fortran Compiler (2025). Make sure to install the appropriate version that matches your system architecture (e.g., x64). Visual Studio 2022: Finally, install Visual Studio 2022 (Community, Professional, or Enterprise). Make sure to include the Desktop development with C++ workload when installing Visual Studio, which includes necessary compilers for C/C++ and the build tools for Fortran. 2. Environment Variables:

After installing all components, you need to configure the environment variables so that Abaqus can access the Intel Fortran compiler via Visual Studio.

Set the Intel Fortran Compiler environment: This can be done by running the Intel compiler’s ifortvars.bat or setting the following manually in your System Properties:

IFORT_COMPILER should point to the directory where Intel Fortran is installed (e.g., C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\bin). PATH should include the Intel compiler binaries and the Visual Studio directories (typically something like C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\bin\intel64).

Set the Visual Studio environment:

Add the Visual Studio 2022 MSVC compiler path to the PATH environment variable. You can find the necessary paths under: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\version\bin\Hostx64\x64.

Add Abaqus environment variables:

ABAQUS_BIN: This should point to the bin folder of your Abaqus installation (e.g., C:\SIMULIA\Abaqus\2024\win_b64\. ABAQUS_ENV: Optional, but can be helpful for controlling custom settings (e.g., ABAQUS_ENV=C:\Abaqus\custom_env.txt). 3. Compiler and Linking Settings:

Modify the Abaqus environment file: You’ll need to adjust the abaqus_v6.env file to specify the Intel Fortran compiler as the default compiler for subroutines.

Set the fortran_compiler to the path of Intel Fortran Compiler: fortran_compiler = r"C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\bin\ifort.exe" Make sure the fortran_linker and c_compiler are also correctly set to Intel’s versions. You may also need to adjust the user_subroutine entry to make sure it points to the right location for your UMAT or VUMAT files.

Linking with Intel Fortran: When linking with Intel Fortran, use ifort as the linker for your subroutines. Make sure that the correct library paths are set for the Intel runtime libraries.

For example:

ifort -I$(ABAQUS_INC) -L$(ABAQUS_LIB) -L$(IFORT_LIB_PATH) -o your_subroutine.obj your_subroutine.f90 4. Known Issues and Workarounds:

Visual Studio 2022 Compatibility: Some users report issues with newer versions of Visual Studio (such as 2022) when combined with certain compilers. If issues arise, check the Intel Fortran documentation for any known compatibility problems or patch notes specific to Visual Studio 2022.

Intel and Abaqus Compatibility: There can be version-specific issues between Abaqus and Intel compilers. Make sure to check for any patches released by SIMULIA for Abaqus 2024 that may address Intel Fortran 2025 integration.

Fortran runtime library issues: If there are runtime linking issues with Fortran libraries, ensure that the runtime paths for Intel libraries are correctly added to your environment. You may also need to explicitly specify library paths in your abaqus_v6.env configuration.

Debugging: If compilation issues persist, check the error logs generated by Abaqus to identify any missing dependencies or misconfigurations. You can also run the Intel Fortran compiler’s ifort with verbose flags to gather more detailed information about the build process and pinpoint the issue.

5. Final Verification:

After configuring everything, perform a simple test by compiling and linking a basic UMAT or VUMAT subroutine to ensure that the setup is working correctly. Use the Abaqus command line to run the job and verify that your subroutine is being called without errors.

By carefully setting the environment variables, adjusting the compiler and linker settings, and ensuring all necessary paths are included, you should be able to successfully link Abaqus 2024, Intel Fortran 2025, and Visual Studio 2022. If you continue to experience issues, it may be helpful to contact the technical support teams for Abaqus, Intel, or Visual Studio to troubleshoot further.

To ensure compatibility between Abaqus 2024, Intel API 2025, and Visual Studio 2022:

• Check Abaqus documentation or the official website for support of these versions.
• Properly set environment paths (PATH, LIB, INCLUDE).
• Update the Abaqus configuration file to reference the correct compiler locations.
• Install the latest updates for all software.

Could you solve it? Because I have probably old version of VUMAT code, and I have an error as : "Error in job plate_impact: Problem during linking - Single Precision Abaqus/Explicit User Subroutines. This error may be due to a mismatch in the Abaqus user subroutine arguments. These arguments sometimes change from release to release, so user subroutines used with a previous release of Abaqus may need to be adjusted."

When I run a simple subroutine that I created, it works. It pass for all validation stages. Perhaps, I need to update the code for current version of the abaqus.

Hi, at the end did anyone got this setup working? I am really struggling to get the link working
