#%% Magnesium HCP. Optimize the cell volume and shape using different constraints.
#%% Checks whether the stresses are symmetric, and whether the optimisation algorithm does
#%% not break the symmetry.
#%% Also checks the possibility to disable the stop after violation of the condition related to dilatmx.
#%% This is done in dataset 6. The optimization delivers acell values slightly different from those of dataset 2.
