Yes. GEO_OPT relaxes only the atomic positions while the cell parameters are kept fixed. CELL_OPT relaxes both concurrently.

Betreff: [CP2K:15350] GEO_OPT and CELL_OPT difference

Hi everyone,

What is the difference between RUN TYPE: GEO_OPT and CELL_OPT ? Since both are doing optimization.

Can we do GEO_OPT for crystal lattice ?
