Hello,
I want to run ANSYS APDL code from MATLAB. When I insert the following line:
dos('ansys192 -b -i input_file.dat -o output2.txt');
However, I get the following error: 'Launch' is not recognized as an internal or external command, operable program or batch file. I have the same problem when I add "ansys_path = 'C:\Program Files\ANSYS Inc\v192\ansys\bin\winx64\ANSYS192.exe' " instead of just "ansys192".
What does this error mean exactly, and how do I get it to work?

Hi Lara,
The error that you are encountering might occur when the command prompt is unable to recognize 'ansys192' or when the path to the executable is invalid. To troubleshoot this error, you can try the below-mentioned steps:
  1. Verify that the executable 'ANSYS192.exe' is present in the path mentioned.
  2. Verify that there are no typos in the path and the file names.
  3. Run 'MATLAB' as an administrator to make sure that MATLAB has the required permissions to run ANSYS.
  4. You can try using 'system' instead, which perfroms the same functionality as 'dos', by referring to the following documentation: https://www.mathworks.com/help/matlab/ref/system.html
Hope this helps!
