<div dir="ltr"><div>Dear</div><div>RMC</div><div><br></div><div>I want to simulate a SiO2 amorphous structure of 432 atoms in a supercell of side 18 amstrongs. However, I just have the oxygen K-edge spectrum, and whant to constrain the first O-O and second Si-O coordination shells. The question is how can I simulate the long range order over such a large supercell beyond the fist and second coordination shells.</div><div><br></div><div>regards.</div><div><br></div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">
