<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Also note that you have one sodium atom and you did not set tot_charge to +1. So you are actually modeling Na+ and an electron. It is very difficult to predict the outcome of this
calculation (metallic solution vs. insulating one) in a vc-relax calculation. If your goal is to model Na+, then tot_charge=+1 guarantees an insulating solution and as such no large smearing is needed.<br>
