[Pw_forum] NLCC with vdb pseudopotentials

[Erik Santiso]

Dear pwscf users,

I've been trying to run some scf calculations on simple hydrocarbon
molecules using pwscf with vdb pseudopotentials. Before using pwscf, I was
working with the CPMD code. I found that whenever I use a vdb
pseudopotential that was generated with non-linear core correction, pwscf
gives me different results. I also have trouble converging 'relax'
calculations when nlcc is included. Has anybody else experienced the same
kind of problem? Do you know of a solution, other than generating the
pseudopotentials again without the nlcc? Thanks!
