Good point. I tried also with Castep 7.0 (same pbesol but onthe fly pseudo)
and it cannot reach convergence. Just increase and eat RAM without reaching
any convergence.
Anyway, I run also the same two inputs also on the 4.3.2 version and the
results are almost the same. Below I report them for comparison.
I'm confused....
pw.x 5.1.1: ecut60_kp222_opt.out
