Dear QE users,

Do we need to mention cell_dofree in the case of calculation = "relax" ?

I need to relax only the atomic positions so I chose calculation = "relax", but it is written in the input file description of pw.x that the default value for cell_dofree is "all" or this only if vc-relax is chosen ?

And when I run two calculations 1st with "vc-relax" and the 2nd with "relax" it is taking the same time while I expected "relax" to be faster

Thank you

Best Regards
