[Wien] Minimization before Volume Optimization ?

[Abderrahmane Reggad]

Thanks Mr pieper for the rich information .

So , I have to minimize the atomic positions of the new low symmetry
structure
with respect to internal forces, or energy.

Now the question is:

Is there any difference between using the internal forces or the energy ?
or it's the same ?
