<br>
If the convergence can be achieved properly with 0.2 and 0.01, then the results should be identical.<br>

Subject: [Wien] Basic question regarding mixing parameter & force optimization<br>
<br>
Dear Wien2k users,<br>
<br>
I have few questions regarding mixing parameters & force optimization<br>
(1) If we reduce the mixing parameter from 0.2 to say 0.01, whether the convergence will come slowly?<br>
(2) Whether it will be accurate?<br>
(3) If we do not get force convergence with PORT should we go for NEWT/NEW1?<br>
<br>
Any response will be eagerly awaited.<br>
<br>
with regards,<br>
<br>
