I have a python code in a program that opens a cmd window and runs there another program. The code looks like:

```
os.chdir('C:/Abaqus_JOBS' + JobDir)
os.system('abaqus job=' + JobName + '-3_run_rel2 user=FalseworkNmm41s interactive')

```

Now everything works but I get an error in the cmd window and next it closes very quickly not letting me see what was the error.
How can I prevent this cmd window to close?
