<div dir="ltr">Dear Prof. Marcelo,<br><br>Thank you for the help message. Interestingly, smearing helped in the convergence, even using mixing_beta at default values.<br><br>Regarding the ecutrho: on the Input File Description site for pw.x, a larger ecutrho is recommended for USPP (about 8x to 12x ecutwfc, I usually put 10x ecutwfc). Although ecutrho for PAW-PP is often 4x ecutwfc, I'll do convergence tests to better adjust this variable.<br>My first point is only to make sure that a single scf convergence is obtained. Probably, in the vc-relax calculations, Na atoms in my structure will be moved and other variables (such as smearing) will be analyzed again.<br><br>Kind regards,<br><br>Bruna<br>-- <br><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span style="font-family:arial,helvetica,sans-serif"><span style="color:rgb(0,0,0)"><span style="background-color:rgb(243,243,243)"><font size="2"><span>Dra.
