<div dir="ltr">Hi All,<div><br></div><div>I am very new to DFT calculations and Quantum Espresso. I am using the Quantum Mobile Aiida Quantum Espresso distribution to perform scf DFT-D3 calculations for ROY structures, however the energy I am getting is very low (~-40000 eV). The parameters file for the calculation is the following:<br><br>parameters = {<br> 'CONTROL': {<br> 'calculation': 'scf', <br> },<br> 'SYSTEM': {<br> 'ecutwfc': 47., # wave function cutoff in Ry
based on the values of the SSSP pseudpotentials<br> 'ecutrho': 360., # density cutoff in Ry based on the values of the SSSP pseudpotentials</div><div> 'vdw_corr': 'DFT-D3',<br> },<br>}<br><br></div><div>I have also selected a 4x4x4 kpoints mesh. <br>Can you provide any insights of what is going wrong? <br><br>Many thanks!</div><div><br></div><div>Nikos<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><br></div></div></div></div></div></div>
