<div>Hi Everyone,</div><div>I've been trying to get the potential energies and forces for a certain number of atoms at different mass densities, from high to very low, under PBC. I've realized that as the cell size gets larger (going to the lower densities) the computational time and particularly the required memory increases. Now I have a cell with the length of 60
<span>Å</span>
and it can not be run because it asks a lot of memory. I wonder if there is any correlation between the cell size and computational time/required memory and if so, how it scales. I should say I could mange to run the case with the cell size of 50 x 50
x
50
<span>Å. Thanks.</span></div><div><span><br></span></div><div><span>Best,</span></div><div><span>Mostafa<br></span>
