title: Run script using a certain version of Abaqus
body: <p>I want to run a python script without Abaqus GUI and this already works well with the command:</p>
  
  <p><code>abaqus cae nogui = scriptname.py</code></p>
  
  <p>As I want to include a subroutine I have to run it in <code>Abaqus version 12-1</code> but I have also <code>version 13-1</code> installed (running the script in cae, I always got an error while using 13-1 but not with 12-1).
  With the command above I don't know which version will be used. Is there a way to specify the used version in the cmd?</p>
