[QE-users] "CALL forces()" for PAW potential Does not work

[Mpayami]

Dear Prof. Paolo Giannozzi,

Hi.
Kindly, when using USPPs then uncommenting "CALL forces()" line in QEROOT/PW/src/electrons.f90 calculates the forces at each iteration step.
However, when using PAW-PPs, it returns "**************************************" instead of numbers.
I would be grateful if you please help me to manage it.

Best regards,
