Debug Abaqus Subroutines
Enable debugging feature in Abaqus
Go the the Abaqus configuration file abaqus_v6.env or win86_64.env in the Abaqus path, for me, it locates in the following path:
The file is like this:

Uncomment all the lines that end with comment of Debugging.
Insert some extra codes to pause in your subroutine when running Abaqus
Add some codes like this to pause at the subroutine after the declaration of variables, like this:
!-------------------------- FOR DEBUGGING ------------------------------------
LOGICAL :: FIRSTRUN = .TRUE.
INTEGER TEMPVAR
IF (FIRSTRUN == .TRUE.) THEN
WRITE(*, *) 'PLEASE INPUT A VALUE:'
READ(*, *) TEMPVAR
FIRSTRUN = .FALSE.
END IF
TEMPVAR = 1234
Run Abaqus command to submit the job
Use the Abaqus command to submit the job, like this
If you have added some code to pause in the subroutine, the program will stop in the command window, like this
10/30/2021 11:51:14 PM
Begin Analysis Input File Processor
10/30/2021 11:51:14 PM
Run pre.exe
10/30/2021 11:51:17 PM
End Analysis Input File Processor
Begin Abaqus/Standard Analysis
10/30/2021 11:51:17 PM
Run standard.exe
PLEASE INPUT A VALUE:
Attach to process in Visual Studio
Open your subroutine file in Visual Studio, click Debug -> Attach to Process, choose the Abaqus program standard.exe or explicit_dp.exe.
Resume running the subroutine and debug in Visual Studio
Add a breakpoint in the subroutine file in Visual Studio, resume running the subroutine in the command window, i.e., input the temporary value, the subroutine will stop in Visual Studio, and now you can debug your subroutine in Visual Studio!
Warning
Abaqus CAE cannot be opened if the debug mode is activated, change the configuration file to the old version and you can open Abqus CAE again.
