How to make Matlab wait for complete process of Ansys Fluent?

I trying to link Matlab with Ansys Fluent, but when I use the command "!fluent..." in Matlab the script don't wait for the final process of Fluent. How can I make it? I need the result files of Fluent to continue the work.

Thanks, Rafael

Hello Rafael,

I don't know much about ANSYS Fluent. But I have some experience with ABAQUS.

To check if a ABAQUS simulation is done or not we can read a .sta file (or .log flle).

Usually, its name is Job-1.sta where Job-1 is the name of the ABAQUS job.

The job is done If the two end-lines of the file contains the following string

THE ANALYSIS HAS COMPLETED SUCCESSFULLY

Belows is a small script to do that verification. Hope that it will help you.

Best regards,

Nhan

idletime  = 0;
flag = 1;
while flag
    fid = fopen('Job-1.sta','r');
    while ~feof(fid)
        tline1 = fgets(fid); 
        tline2 = fgets(fid); 
        keystr = 'THE ANALYSIS HAS COMPLETED SUCCESSFULLY';
        if contains(tline1,keystr ) || contains(tline2,keystr)
            flag = 0;
            fprintf('Running time = %d (s)\n',idletime)
            break;
        end
    end
    fclose(fid);
    
    pause(1);
    idletime = idletime + 1;
    
    if idletime > 600 % 10 minutes
        fprintf('Waste idle time = %d (s)\n',idletime)
        error ('Too slow simulation (> 10 minutes). Please recheck your code');
    end
end

Thank you so much, I was going crazy trying to guess the Abaqus simulation time with a simple "pause()". This helped me a lot!

Hello Rafael

you can use the Matlab aas toolbox to connect to local/remote Fluent session

The toolbox is now availabe for download from Mathworks File Exchange at

https://www.mathworks.com/matlabcentral/fileexchange/155122-ansys_aas-1-1-13

You can stream the Fluent commands from your Matlab script. When you are done streaming you can shutdown Fluent from matlab using the terminate command
