<br clear="all"><br> Dear Paolo<br><br>Thank you for reply.<br><br>With ecut = 72 Ry , I repeated the simulation five times. The simulation proceeded<br>several scf iterations and several bfgs iterations but the jobs were never finished. ( I attached one of the out puts. )<br>
<br>Is it possible the ecut is so great that RAM is not sufficient for 3-atoms cluster ?<br><br>Best regards. <br><br>Reza.Shidpour<br>SUT<br><br>
