Dear B.Arunachalam,<br>
<br>
from what I can understand, calculation='relax' needs to be set in the <br>
&CONTROL namelist, which then triggers the &IONS namelist to be read and <br>
not ignored (as reported).<br></blockquote><div><br></div><div>exactly so. In addition, these options are supported only in CP, not in the self-consistent code:</div><div><br> ion_velocities='zero',<br> ion_radius(1)=1.0,<br> ion_damping=0.01</div><div><br></div><div>Paolo</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
hope it helps<br>
take care<br>
