Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel oneAPI

Prafull_Bhosale_IITB — Sat, 19 Feb 2022 08:07:59 GMT

Download and install Visual Studio Build tools 2022 with default options checked. (DO NOT UNCHECK OR CHECK ANY OTHER OPTIONS.)
https://visualstudio.microsoft.com/downloads/?q=build+tools
Install Fortran compiler from this website

https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html

Install Math kernel Library also from above website

Add following in paths in Path environment variable in system:

C:\Program Files (x86)\Intel\oneAPI\compiler\latest\env\

C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build

Add following lines in abaqus.bat file

call "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build\vcvars64.bat"

call "C:\Program Files (x86)\Intel\oneAPI\compiler\2022.0.2\env\vars.bat" -arch intel64

call "C:\Program Files (x86)\Intel\oneAPI\mkl\2022.0.2\env\vars.bat" intel64

To check if linking is done, run:

First open Abaqus Command prompt and then enter following:

abaqus info=system

Output should be like shown below:

To check if fortran file is running:

First fetch a sample file from Abaqus repository.

abaqus fetch job=std_user

This command will fetch sample file with user subroutine from Abaqus repository and put it in current directory.

*******IMP step: Remove the commented lines; otherwise, the program will not work. This is due to some bug in intel oneAPI *********

std_user.for file after removing commented lines should look like as shown below:

abaqus job=std_user user=std_user.for

Check std_user.log file. It should have "Abaqus JOB std_user COMPLETED" at the end of file.

******DONE**********

Please show the source file before the commented lines are removed. I am curious to know what the perceived bug is. (I am not an Abaqus user.)

Why this complier can not compile subroutines contain ABA_PARAM.INC?

Like Steve, I do not use Abaqus, I merely know of its existence. As you do not indicate what the compiler complains about and why it fails to compile such subroutines, I can only guess what is going wrong: it cannot find the include file "ABA_PARAM.INC". You need to specify its location to the compiler, if that file is not in the same directory as the source file.

Thank you for you help.

Abaqus compile the subroutine correctly and the analysis started, but then the analysis aborted and there is no results at all.

Re: Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel on

Hayel — Mon, 02 Jan 2023 02:31:54 GMT

This analysis is completed before in Abaqus 2017 and the link with VS2012 and Intel composer EX 2013. So why it is aborted in Abaqus 2022?

Re: Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel on

Arjen_Markus — Mon, 02 Jan 2023 09:01:37 GMT

First of all: you may want to start a new thread, rather than continuing with this old one. It will allow you to give it a more appropriate title.

You do not give us much clues as to what is going on and wrong, I am afraid. Apparently, there are at least two components that are different from your working version: Abaqus went from version "2017" to "2022" and the Intel Fortran compiler evidently changed also. As I do not know Abaqus, I have no idea if that is responsible for the observed failure. But be aware that newer versions of compilers can bring out lurking mistakes and errors in programs.

Given that you do not indicate HOW the analysis is aborted (nor show any code), I can only give you general advice:

Try to find out if the analysis program printed a stacktrace, so that you can at least get some information on what went wrong.
Lacking that, try with an empty routine, possibly merely printing a message to a file on disk, so that you know it has been called.
If that succeeds, add print statements in the routine to see where it fails. At some point you may see the exact location - or, if you are unlucky, the problem will have gone. The latter is usually an indication that something like an uninitialised variable caused a runtime problem (accessing an array way out of bounds for instance).
What you can also try is creating a small program that simply calls your routine with the right set of arguments, to see if in such an isolated case things work or do not work.

Just very general advice ;).

hi,

I am following the same steps on Abaqus 2022, VS:2022. but facing problem of linking Fortran compiler after typing "Abaqus info=system" in cmd window.it shows

this is for the path.

please help me in resolving the issue

andrew_4619 — Wed, 01 Feb 2023 12:23:27 GMT

The ABAQUS comment is not quite correct anymore. in the command window run C:\Program Files (x86)\Intel\oneAPI\setvars

and see if that helps.

i have to add this in "C:\Program Files (x86)\Intel\oneAPI\setvars" in Abaqus bat file

Re: Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel on

ALOK_05 — Thu, 02 Feb 2023 09:24:26 GMT

I am able to resolve this issue by adding the "vs 2022" after intel64 in abaqus bat file, but currently iam facing problem with verification. after typing "Abaqus verify -user_std"in cmd window.

Steve_Lionel — Wed, 15 Feb 2023 15:05:53 GMT

The failure to find user32.lib, which is a Windows API library, suggests that you are not correctly establishing the compiler build environment. You earlier wrote about adding a call to setvars.bat, which should do this. As you are showing us only the error output and not what led up to it, it's difficult to comment further.

hi steve,

thanks for reply.

i have followed the whatever step is suggested initially . I am able to link Fortran with Abaqus

the result after typing "abaqus info=system" in cmd window.

the reuslt after "abaqus verify -user_std" in cmd window.

Getting this after "std_user.log file" in cmd window

I hope I am to show the what leads to error. if any further information is required i am happy to share

Re: Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel on

andrew_4619 — Wed, 15 Feb 2023 15:51:32 GMT

You would need to look at the link command used. There is the possibility of some libabry path direction on the link command or it gets this from the environment (path). Maybe the log file mentioned will help?

Anyway a Steve days user32 is a windows system library and does not have much to do with the "user subroutine" you are trying to build.

I'd remark that this is an ABAQUS issue, not an Intel compiler issue.

@ALOK_05, did you see this post, How to Use Intel's Fortran Compiler with Abaqus? Maybe there is info there to help you.

Re: Linking Fortran compiler with Abaqus (minimal required installation; no need to install Intel on

Steve_Lionel — Thu, 16 Feb 2023 15:54:23 GMT

@ALOK_05 , sorry, I have never used ABAQUS. If you have an issue with the Intel Fortran compiler that shows when not invoking it from the unseen ABAQUS bat file, feel free to ask here. Otherwise please contact ABAQUS support.
