During a study tour abroad
Time spent at another research institute or private research company should be organized so that you have the time for research, courses, knowledge outreach, etc., during your stay.
Be aware that working conditions for PhD students differ very widely between countries. Whereas in Denmark you would be in a research environment with office facilities, as a PhD student in other countries you may be left to your own devices.
Remember to make an agreement with your supervisor about how and how much you should stay in touch while you are away.
