[CP2K-user] [CP2K:10795] Transition state search with DIMER METHOD

[Stefano Pantaleone]

Hi Luca,

thank you very much for you fast reply. This is quite strange for me. In my
experience of TS search, it is mandatory to give to the algorithm the
direction to follow along which the energy has to be maximize, otherwise
the algorithm go to reactants of products. I do not have a good starting
geometry; in this case I suppose the best way to proceed is a NEB. I
preferred to avoid NEB because it is quite expensive, so I tried with DIMER.

Thank you very much,
Stefano
