MEAM, zbl=1 -blend the MEAM with the ZBL potential for small atom separations

Don’t worry. I didn’t need to do it. I did it, because it was a nice opportunity and a very good example to showcase the process. Since the forum is archived, this will hopefully be found by others in the future that are looking for ways to figure out something through the same procedure.

Unlike other people that have trouble following the conventions for such a forum, you did three very important steps correctly: 1) you did research on your own before posting and documented that, 2) you described your problem concise and sufficiently complete, 3) you flagged your post as a “beginner level” topic, thus my “beginner level” response.

I am always happy to spend time and responding to such topics, because it can be a positive example for how this forum can work (unlike arguing with people what kind of information the must provide or what it is that they want to do and them not explaining what they did so far), and it is by far less effort to sort out a well posed question that is easy to understand, or at least make a decent attempt.
