Dear Ben,

use GeometryConstraints together with constr.f file where you can code your symmetry constraints. You have to recompile the code then you have automatically a symmetry constrained relaxation. Lev Kantorovich's package can be very useful to construct the relevant constr.f file that can be freely downloaded from the web.

Yours,
       Adam Gali
