Running Abaqus from Matlab

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=jobThe 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.

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 ?

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.
