[Pw_forum] B_field

[Gabriele Sclauzero]

It seems to me that B_field can be read from input, but then is not used in the 
calculation. Maybe it was an older option which has been replaced by another solution. In 
fact I think that a better way to see the effect of an external magnetic field is to do a 
calculation with constrained magnetization (see INPUT_PW for documentation): this should 
ensure to reach the ground states, while I suspect that applying a magnetic field you 
could end in a metastable state, depending on the starting conditions.
