Hi My dear friend

It seems that you are encountering two separate issues. Let's address them one by one:

If you continue to encounter issues, I recommend consulting the Abaqus documentation or reaching out to their support for further assistance, as they can provide specific guidance related to their software integration.

Hi dear Yousef Bahrambeigi

Thank you for your response.

The two cases you mentioned are exactly related to the mentioned error and I have already solved the errors.

I have already added the path of C++ compilers including VC++, gcc and g++ in windows system variables. And I produced different software with it.

Abaqus used relative paths to define the header, and I introduced the absolute path to Visual Studio. After fixing it, it showed the following error:

The code execution proceed because ABQSMABasCoreUtils.dll was not found.

This issue was previously discussed in stackoverflow, but unfortunately it was not resolved.

Vahed Mam Ghaderi Hi

and with Best Regard

only way that i know maybe help you :

Check DLL dependencies: ABQSMABasCoreUtils.dll may have dependencies on other DLL files. Use a tool like Dependency Walker (http://www.dependencywalker.com/) to analyze the dependencies of ABQSMABasCoreUtils.dll. It will help identify if any other DLL files are missing or not properly loaded. Install the missing DLL files or ensure that they are correctly configured.

or reinstall Abaqus Software.

I am Glad to meet you in near future.

with Best wishes

• Hi again Vahed Mam Ghaderi
• According to this answer, you should not use the main function as the entry point for your program, but instead use a function named ABQmain with the same signature as the regular main function. This is because the Abaqus ODB C++ API requires some initialization and finalization steps that are performed by the Abaqus libraries before and after calling your ABQmain function.
• According to this answer, you should also make sure that you have added the Abaqus ODB C++ API DLLs to your system path or copied them to your project directory. These DLLs are located in the C:\SIMULIA\EstProducts\2023\win_b64\code\bin folder. You can check if they are loaded correctly by using a tool like Dependency Walker or Process Explorer.
• According to this question, you should also avoid opening the ODB file in read-only mode if you want to save it later. You can do this by passing readOnly=False as an optional argument to the openOdb function.
