[Pw_forum] Default values used in Quantum espresso manuals

[Duy Le]

Hi,
conv = convergence
thr = threshold
forc = on the force
etot = on the total energy

So, the keywords say everything. They are the convergence threshold or
convergence condition. They are arbitrarily defined as users' needs. The
default values are the conventional values, I guess.

Best,
