[Wien] Question regarding volume optimization

[shamik chakrabarti]

Dear wien2k users,

    I have a query regarding volume optimization in wien2k. "Option 1"
optimizes the volume by keeping a:b:c = constant. Now my question is:

in which case this "Option 1" is applicable?...is it only applicable for
cubic symmetry?

Any response in this regard will be helpful for us. Thanks in advance.

with regards,
