Hi friends of the list.<br>
<br>
I amt trying to simulate a linear chain (single atom for the moment, and I put the following input. I put the following input:<br>
<br>
&system <br>
ibrav= 14,<br>
a=2.80, b=12, c=12,<br>
cosab=0.0, cosbc=0.0,cosac=0.0<br>
<br>
Is this correct? Since PWSCF takes advantages of yhe symmetries, I
don't know if I am doing 'the best' election for the ibrav.<br>
<br>
<br>
Best wishes<br>
