Hi All, i would like to use Matlab to send a job to the Abaqus solver and to specify 24 processors for this process. I normally do this using a batch file containing this: 'abaqus job=jobname cpus=24 interactive' but would like to do same using command window. At the moment, the code i am using is below but I don't see any difference in the computational time with and without adding 'cpus=24' unlike when use the batch file. Please any suggestions would be very helpful. Thanks in advance.
cmd_str = ['abaqus job=', jobname, ' input=', jobname, '.inp', 'cpus=',24];

you have a slight typo in your code, you are missing a space in between ".inp" and "cpus" Try this code instead:
jobname = 'put your job name here' cmd_str= ['abaqus job=', jobname, ' input=', jobname, '.inp', ' cpus=',int2str(4)] system(cmd_str);
I would recommend to use the int2str function for the cpu numbers, and then you can control the number of cpus with Matlab as well. This code works for me.
