Running Abaqus from Matlab

193 views (last 30 days)
Hi All, I have a MATLAB script that generates an .inp file that is sent to the Abaqus solver through the command window by using the line of code below:
dos(abaqus job=job.inp) %or
!abaqus job=job
The high level script is a while-loop and because it involves several iterations, Abaqus inputs files with different names are generated at pre-specified intervals (e.g. job1.inp, job2.inp, job3.inp, etc all created in the working folder). The challenge I am having is how to send these input files with different names to the command window. I have observed that the ‘dos’ statement above can only take ONE input value after the ‘=’ . Please your advice on how to solve this problem will be appreciated. Thanks in advance.

Hod did you generate an .inp file? I generated this plot and I want to export this structure into Abaqus.
Best regards

The following works under Linux. The command system should work to replace either dos or unix.
n = 3;
for k = 1:n
jobname{k} = ['job', num2str(k)];
end
for k = 1:n
cmd_str = ['abaqus job=', jobname{k}, ' input=', jobname{k}, '.inp interactive'];
disp(cmd_str);
system(cmd_str);
end
outputs:
abaqus job=job1 input=job1.inp interactive
abaqus job=job2 input=job2.inp interactive
abaqus job=job3 input=job3.inp interactive
Does this work for you?

Is it possible to run the abaqus jnl file through matlab instead of the inp file ?

Hi all,
I am working on heat transfer MATLAB input file that will be used in Abaqus.However, I am getting error message "abaqus command line option "input" must have a value". Any one any idea?
Thank you in advance

The suitable syntax if the name of the job is JOB and the name of the input file is INPUTFILE.inp is:
!abaqus job=JOB input=INPUTFILE
or
system('abaqus job=JOB input=INPUTFILE')
For more information you can refer to the Abaqus2Matlab toolbox.
