Hello all users,

I read some about creating data file but I couldn’t clearly get how to generate thousands of atoms coordinates. For example I am trying to model water-copper nanofluid and I modified a data file that I’ve found in here to study on it. That was the data file of gold-water nanofluid, it looks very succesfull on VMD, so I changed the mass and the potential of gold particles leading to a copper model; however, that data file contains about 8000 atoms which is huge for preliminary analysis causing very long runtime and I want to obtain a smaller configuration as data file. What is the best and the most practical way to obtain a data file with desired coordinates dealing with the positions of all the atoms. Thank you for your attention.
