Hello,
I have seen the file: Structures | glasses | SiO2_21A_3d.msi
But I am not sure if it is OK to use this structure, since I don't know how was it generated, nor how to describe it in a report that I did not generate it but took it from the available files (I cannot find any information about the files in the structure folders).
I would like to use this file instead of generating my own, since it does require a long simulation time to anneal a crystal silica block, but I will have to do it if I don't know how the reference such file.
Thanks
