Dear Ehsan targholi,<br>
<br>
Keyword here is "pseudo potential" (QE), versus (probably) all-electron calculation in Dmol3. In practise one is almost always interested in energy differences between different systems but the same approach, and thus total energies never appear there.<br>

hi to every one<br>
Dear all<br>
i have a serious problem. when i performed the attached input calculation<br>
with ESPRESSO, i gave the total energy equal to -71.43856899 Ry that is very<br>
different with output of Dmol3 software that gave the total energy equal to <br>
-210.165297Ha ( -420.330 594 Rydberg [Ry]).<br>
the same calculation input has been used for both software.<br>
I am quite confused.<br>
<br>
<br>
best regard<br>
