CCL: structure of amorph silica, simulation

 Sent to CCL by: "Azin Naghmeh Azarkamand"
 Dear CCL'ers
 I am writing in order to find the data for forming the structure of amorph
 silica. I would like to form this structure but since every work that has been
 published involved the simulating of the mentioned structure and  I have not
 worked with simulation programs before so I would be grateful If you could
 supply me with this data.
 Thanks in advance
