When you perform a structural optimisation on a crystal system is it considered a Lattice Statics or Lattice Dynamics calculation?

As I understand it, phonon calculations and elastic modulus calculations, for example, **are** Lattice Dynamics, as they are modelling atom movement, but I’m not sure about structural optimisation. The atoms do move throughout the process, but is it right to say the calculations don’t take into account any movement, thus making it a Lattice Statics method?
