Dear all,

When i change the total number of atoms in my unit cell from 91 to 159,
the memory(estimated) changes from 5.2GB to 15 GB!
the number of plane waves changes from 15,000 to 28,000.
so the memory shud actually get doubled(roughly)..

then why is the memory changing by almost 3 times?

Best regards,
Jaita.
