What material will expand after being compressed?

I think you need to know the potential energy surface (PES) of the system. Assuming the system is in equilibrium before applying the deformation, any modification will take it to a non-equilibrium sta …

Is it necessary to do self-consistent calculation after structure optimization?

The procedure that takes more time to finish is the geometry optimization (in each step there are self-consistence field calculations). There are properties that can not be calculated at the same time …
