Re: [Pw_forum] lelfield=.true. with USPP , PAW and non-orthorhombic cells
Thank you Prof. Giannozzi. I tested running PWscf to calculate the ground state of monoclinic ZrO2 under finite homogeneous electric field using PAW PP. I could not find error messages in the output file to warn against using PAW PP. After the first electronic step, I can see the Berry phase calculations running smoothly. I'm using the latest version of Q.E. , v.5.1.1. and below is the input file I used. (The PAW PP are from the PSLIB.) Thank you for your help!
