Matlab is busy after running system() command
显示 更早的评论
Hi everybody,
I am running a cmd command via matlab using
system(cmd)
where cmd is my command and is starting a programm (Ansys Workbench).
However, after the program is loaded Matlab is still busy. Is there an alternative option to run a system command?
Running a batch file would also be ok. If I manually start the program with the batch file and then starting my Matlab script, everything works fine.
Thanks in advance and best regards
Felix

Hi Felix,
In order for the MATLAB not to be busy, you have to close the program and then you can resume to work in MATLAB.
There's also an option that tells MATLAB not to wait for the program to be closed if you add the '&' symbol.
cmd = 'C:\...\_exe &';
system(cmd)
However, you should be (this is useful if you want to interact with simulation settings etc.) working with external API for ANSYS through the COM server. See actxserver function and documentation on API in ANSYS.

Note that if you use the & at the end of the command, then system() will return as soon as it starts the Ansys process successfully, without waiting for Ansys to do any useful work.
In some cases you can meaningfully use & to do some pre-determined work, by creating a file of input for the command and redirecting input from the file. In other cases, though, there is a fair bit of difficulty getting the process to do specific things commanded by MATLAB.
Using the actxserver to command Ansys offers a lot more control.

Yes, but '&' won't get you anywhere if you are looking to get some results out of program. If you want to run it in batch mode as it looks like, here's a better way to do it, instead of system command.
I can't tell how to start ANSYS in automation mode, but you need ProgID for it, which you can get from documentation or you could Google how to find ProgID. Example with Excel, I tried to open ANSYS in the same way, but it doesn't work.
excelCOM = actxserver('Excel.Application')
