Hi,
I am using MATLAB to run OpenSeesSP.exe. Typically, I use the below code to run OpenSees using single core and it runs in MATLAB command window
system(['OpenSeesSP ' 'fileName.tcl']);
To run OpenSeesSP using multiple cores, I use the following code. However, OpenSeesSP runs in an external cmd window
!"C:\Program Files\MPICH2\bin\mpiexec.exe" -np 5 OpenSeesSP.exe fileName.tcl &
What should I use to run OpenSeesSP with multiple cores in MATLAB command window not in an external cmd window. I tried the below line of code but it did not work.
system(['"C:\Program Files\MPICH2\bin\mpiexec.exe" -np 5 OpenSeesSP.exe' 'fileName.tcl']);
Basically, I am gonna use this command in a for loop where I need some output from OpenSeesSP to proceed with the for loop. Thus, I need MATLAB to wait until OpenSeesSP completes its analysis.
Thanks!

Please explain, what "did not work" means. The details matter to understand, what the problem is.

Hi, I'm run OpenSeesSPv2.4 with a parfor (run each model with 2 cores, and run simultaneusly 4 models). I use this code lines for run OpenSeesSP since matlab.
% Run the model.
% -------------------------------------------------------------------------
oldFolder = cd(Path_current);
command = ['mpiexec -n 2 OpenSeesSP_x64 Dynamic_Analysis.tcl'];
[status,~] = system(command); % Run OpenSees.
cd(oldFolder);
I hope that it will help you.
What is your OpenSeesSP version?, I need a current version of OpenSeesSP, at least a version that allow run a model with 6 inputs ground motion (3 translational with 3 rotational).
Bests, M.
