I have done a hybrid/co-simulation simulation. Motionsolve, Activate and Isaac sim are solving together. Motionsolve & Activate are started with this process = subprocess.Popen(command, shell=True), but I have no idea how kill the the subprocess when the stop button is pushed (omni.kit.commands.execute(‘ToolbarStopButtonClicked’)). I know how this done in Python code, but Omniverse is making this one more difficult. Any ideas ?
