Hi

yes, there is a bug in the GAPW code for meta functionals.
You can also call it an inconsistency in a local expansion.
In the latest version, some of the problems have been fixed,
but there are still some problems remaining.
It is on my todo list, unfortunately not very high.

regards

Juerg

Which version of cp2k are you running? Could you try updating to the latest version (2.6) and see if that improves things?

I got similar output to you with an old 2.5 executable, but 2.6 from mid March converges OK (but with some warnings from qs_vxc_atom).

I am trying to perform all electron calculation(GAPW) with TPSS functional for water dimer.
The wave function is not converging at all. This all electron input work fine for PBE, BLYP functional. It also works for GPW with pseudopotentials (TPSS). only the GAPW all 
electron calculation with TPSS is not working. 

I dont understand, why the all electron calculation in not converging for TPSS? 
 
Any help/tips/comments/suggestions would be greatly appreciated.
Thanking you
