Issues running Simulink/MATLAB when running batch file for FlightGear

Hi all,

I have been trying to run FlightGear through a MATLAB/Simulink model with the dos command, and have been running into a key issue.

After starting FlightGear from dos('runfg.bat'), I lose access to the MATLAB and Simulink windows of work. Although FlightGear successfully starts, I am unable to run my Simulink blocks or any MATLAB scripts. As a result, I am unable to drive FlightGear with my Matlab/Simulink model.

Is there a way to run this bath file via dos while being able to compile my Simulink model?

Thank you in advance for any help!

Shown below is my batch file named 'runfg.bat'.

SET FG_ROOT=C:\Program Files\FlightGear\data C:\"Program Files"\FlightGear\bin\fgfs.exe --aircraft=ASK21 --fdm=null --enable-auto-coordination --native-fdm=socket,in,30,localhost,5502,udp --uBody=30 --fog-disable --enable-clouds3d --start-date-lat=2004:06:01:09:00:00 --enable-sound --visibility=15000 --in-air --prop:/engines/engine0/running=true --disable-freeze --airport=KSFO --runway=01L --altitude=8000 --heading=0 --offset-distance=0 --offset-azimuth=0 --enable-rembrandt

I have the same issue as yours. I wonder if you have solved it?

dos('runfg.bat &')

I had the same issue previously. It can be solved by running the FlightGear batch file 'runfg.bat' directly from the windows explorer instead of MATLAB command window. Once your FlightGear starts and you see your airplane or cockpit view, you can run your Simulink model and it will then automatically take you to the conditions set by you in the 'runfg.bat' file and start executing your model.

Yes, it works for me using this approach.

I tried doing that but I keep getting : 'runfg.bat' is not recognized as an internal or external command,

operable program or batch file. this error.
