I want to implement a VUMAT subroutine in Abaqus, but when I do it, the following error displays. Is there anyone who knows what this means?
I use Abaqus 6.12-1 and visual studio 2008. I am sure that they are linked.
"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."
Hi,
For versions 6.10 and upper only visual studio 2008 and intel fortran 10 or
11 are allowed to be linked with abaqus.
As suggested by Aliasger..you should check version of fortran compiler.
Dear Aliasger & Deepak
I use intel fortran 11.1.048 compiler. I test it by examples that exist in abaqus's manual and it works properly.
If so then problem is in your subroutine.Please check VUMAT subroutine in fortran compiler for error.
I attached my VUMAT file, please take a look at it. is there any problem?
Just to make sure that your set-up is right ... have you checked at the command prompt:
abaqus verify -user_std
@ Samarth
I can not understand what should I do. could you explain more?
Yes. .... sorry I gave command for abaqus standard .... issueing this (abaqus verify -user_exp) command at the windows/linux terminal command prompt will at least confirm that everything is fine. Even though your successful execution of test cases somewhat eliminates need for this, I would do that. Especially given that its not that difficult.
Hey
What do you mean from testing the example files? have you linked them and run a simulation which has given an answer?
if so, please put your error tense here completely which will help us understand it. single and double precision will not make any problem unless you define the parameters as Double not Real in the code.
if you have not linked successfully, just check the Windows to be 32 bit not 64 bit because your intel fortran is for 32 bit. it may link when you install but will not work afterwords.
@ Shahram
I debug the program and it works well. I used extra parameter that it was not necessary.
I use sample .for files that exist in the HELP. so I was sure that they are linked.
you know, after you linked the programs you need to copy all Abaqus Library files and all *.inp and *.for files to the same folder. then you can use intel fortran build environment and "Abaqus job=...user =..." command to link correctly.
debugging the code in the VS does not mean that your Abaqus and intel fortran are working with together, you have just linked VS with fortran. you need to link them with Abaqus too.
do you use nay İntel Fortran Build environment? (something like CMD in the windows)
Dear Shahram
I do not know how to build it, could you explain more?
I faced the same problem before, and the way I got over it is by checking the ABAQUS documentation for the new release of ABAQUS that I was using then. I found the verification umat and vumat subroutines provided by ABAQUS documentation and I compared them to my FORTRAN files that were built and linked to an earlier version of ABAQUS. Earlier formats might be different and might cause link errors.
Have you installed intel fortran? I myself use a combination of visual studio 2012, intel fortran composer 2013 and abaqus 6.13 to run umat subroutines. To ensure whether abaqus, fortran and visual studio are linked you must run abaqus verification. Many times the problem of linking is due to the path of system variables and you can learn how to solve it by a quick search in google.
@ Forough
Thanks for your recommendation. Actually this was because of writing a variable that I have not defined it in the code. I defined it, so I could run the program.
regards
Many thanks,
but actually now I am trying first to install Intel Fortran 11.0 supported by visual studio 2005 , 2008 or 2010 express edition . However, they told me your machine has a lack in support visual studio ? has anyone had experience with this problem? please if any help ?
Regards
I have to use a MPC (Multi point constraint) in abaqus. I have a python script file that creates the node connection for MPC and an user subroutine.
1. I initially opened my abaqus file with a part and used Run Script (to run the python code) and then tried to attached user subroutine under job module. is my procedure right???
2. When i submit the abaqus file it is showing Problem during linking - Abaqus/Standard 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. plz can anyone guide me
Hi dear Mohammad
can you tell me exactly what was the problem in your code?
i had a same error and couldn't overcome on it.
Dear Hamid
I used a variable that was not defined in the program.
Regards
Google for example files for Vumat. You can easily understand how to use SDVs
Dear Mohamed
I think you need to use double Precision option in the job.
It seems to me that you have to use for Abaqus/Explicit precision: Double -analysis+packager .
Hi dear Mohammad
can you tell me exactly what was the problem in your code?

Ahmed Boukar
This is because of some issues in my code. I used some variables that was not defined properly. you can send me to debug it.
Use Double Precision as Abaqus Explicit/Precision and Full as Nodal output precision.
As mentioned , you have a problem during linking - Single Precision Abaqus/Explicit User Subroutines. This may be due to MSMPI version. You should install respectively : visual studio 2008, fortran and then Abaqus 6.12-1. For more deatails, check xpl_user_sp.log in C:\verifyOLD by default.
