PBE0 convergence tactics

#1 Post by schani » Thu Sep 09, 2010 8:28 am

Hi all!

I am doing some PBE0 calculations. These seem to converge very well when I first do A PBE run and then use the obtained charge density and wavefunctions as an initial guess for the PBE0 calculation. Actually, it seems to work a bit too well for my taste. Does anybody know if this is a good thing to do or if I am messing up something here by starting from some high-symmetry point?

Yep, this procedure works well. It also tells that your PBE solution is probably reasonable ...

Cheers,

alex
