<br>
How much is the nearest neighbour distance reduced when you reduce from the initial structure the volume by 15 % and afterwards c/a by 9%<br>
(My guess would be more than 10%)<br>
(in addition what happens if you shift the atom with the free parameter)<br>
<br>
Try to initialize the calculation for the structure that causes the nn error and see what happens.<br>
(also try to initialize the structure with the largest volume and c/a reduction.)<br>
<br>
Which atom is affected when you use min ?<br>
How does this influence the nearest neighbour distances (which ones) ?<br>
<br>
What do you finally conclude for your RMT settings ?<br>
<br>
Ciao<br>
