Dear QE - Forum<br><br>I have two problems(one problem and a question)<br><br>First, when i tray to convert the psuedopotential of the mercury using fhi2upf i obtain the next error :<br><span dir="ltr" id=":1o4"><br>Input file > hg.optgga1.fhi<br>
read_fhi: assuming abinit format<br>read_fhi: error reading core charge</span><br><br>Now the question I'm using a aluminum surface and apply an external electric field, I'm using :<br><br> 1 &CONTROL<br> 2 calculation = 'scf'<br>
