<div>Dear wien2k user</div>
<div>I work on a magnetic compound that its magnetic ion is gadolinium.<br>In optimization of one of Gd compounds that its data is experimentally data<br>I don't have any minimum point in E_V when we optimize with -7.5%, -5% ,0% ,5% ,
7.5% of volume. </div>
<div>I have a nearly straight line that we have expected the curve with minimum point. <br>what does it mean?<br>best regards</div>
