Dear Lorenzo<br><br>Thank you to reply.<br>It is always segmentation fault. My system is 3-atoms Au cluster.<br>this cluster forms a chain of atoms but the calculations never finished<br>because of segmentation fault. <br clear="all">
<br>Dear Gabriele<br><br>the work was completely don with kinetic-energy cutoff=32.0000 Ry and charge density cutoff = 320.0000 Ry .<br><br><br><i>Forces acting on atoms (Ry/au):<br><br> atom 1 type 1 force = -0.00009579 -0.00009579 0.00000000<br>
