includestress vs includelattice


Gets Around
What's the difference between

set includestress .true. # tell driver to optimize unit cell
set includelattice .true. # tell driver to optimize with a,b,c,alpha,beta,gamma

I thought stress optimizes a,b,c,alpha,beta,gamma, or is it something else?

Gets Around
By default the cell optimization optimizes the lattice vectors a1, a2, and a3.
