I have installed Avogadro 1.97.0. I am trying to optimize my molecule with some atoms in fixed positions. But there is no option like " Extension-Molecular Mechanics-Fixed selected atoms"
Can anybody please guide me on how to Fix selected atoms in this version?
At the moment, it’s not possible - I need time to finish the new optimization framework… which will probably have to wait until the end of the semester (i.e., late April) at this rate.
