I am trying to run python abaqus through the command prompt using 

os.system('abaqus CAE noGUI=ODBMechens')

It doesn't seem to run anything, but if I go to the command prompt myself and type in

abaqus CAE noGUI=ODBMechens

it works. I am using python 2.7 on Windows 10. Thanks

try using the subprocess module (it's newer) instead: for example, 

subprocess.call(["ls", "-l"])

and in your example, it would be:

subprocess.call('abaqus CAE noGUI=ODBMechens')
