<DIV><BR> Dear PWscf-users,</DIV>
<DIV> </DIV>
<DIV>I'd like to restrict the water molecules within a given distance from the Metal surface, namely, preventing water molecules from leaking out of the interface slab. According to some literatures, confining potentials (usually parabolic barrier potentials) should be applied, does anyone know how to realize it in PWscf?</DIV>
<DIV> </DIV>
<DIV>Thanks & Best Regards,</DIV>
