Dear all,<div><br></div><div>I tried to use the hybrid functionals implemented in the ESPRESSO (B3LYP,PBE0 and HF) in some full optimization calculations(vc-relax) and I don't understand how the nstep variable works. When I perform LDA calculation QE stops after nstep optimizations steps. However,by using hybrid functionals, I don't know how to control the number of ionic steps, i.e., QE continues in the case that the number of steps is larger than nsteps. What can I do?</div>
<div><div>Some suggestions???</div><div><br></div><div>Thanks to all</div><div>Best regard</div></div>
