[ase-users] Relax unit cell with strain

[Protik Das]

Hi all,

I need help regarding a cell relaxation problem.

I would like to strain the structure bi-axially and let the other lattice
constant relax.

For example, I want to strain lattice vectors a and b. Keep a & b fixed and
let the c vector relax. Can it be done using any of the classes from
ase.constraints?

Thanks!
