Appendix A Trouble-shooting

We sincerely hope that FHI-aims will largely “do the job” for you as it comes; in fact, a large amount of work has gone into ensuring sane responses and understandable output from code when something was requested that was not safe or reasonable to do. Nonetheless, as with every piece of software, non-trivial issues can happen that are not immediately obvious to the user. In this appendix, we provide a list of known conditions that have taken unwary users by surprise, how to detect and how to fix them.

If you know of an issue that is not discussed below, but that should be included because it presents an easy stumbling block especially for new/inexperienced users, please let us know, and we will address the issue here.
