[Wien] Regarding Rkmax choosing for molecular crystals

[Peter Blaha]

RKMax=2.5 is probably not really enough. But nobody can tell for sure. You
have to test it yourself and for that you have to set RKMax=3 and
compüare the results.

But check the scf-file, what RKMAX was really used (grep :RKM case.scf).

Note: What you put in the input for RKmax cannot always be used and it might
be that RKMAX gets automatically reduced (see :WAR)
