[CP2K-user] hybrid functional revPBE0-D3 gets stuck with no errors outputted

[Matt W]

I'd suggest starting from a converged GGA calculation. If you screen on 
that initial density you can get a big speed up (though rerun to check).

EPS_PGF_ORB is very tight, you could increase it a bit. EPS_SCHWARZ is also 
quite strict, you could increase it to 10^-7 or even -6 and then check 
convergence when you have a good wavefunction.

+ Juergs advice.
