Dear users<br>In optimization for SiGe with Cubic structure , the minimum energy isn't in agreement with minimum pressure. Whenever for relaxed systems (minimum pressure) the minimum energy should be take place.<br>our energy results (the red points) aren't on the suggestive curve(green line).
<br>1)what is the reasons for occurrence this issue?<br>2)what is the nature of suggestive curve(green line)?<br>with best regards<br>
