character(len=4) :: metals_method

This determines the method used in calculations on metals.

The possible values are:

• NONE - no special treatment of metals.
• DM - metals treated by density mixing.
• EDFT - metals treated by Ensemble DFT.

These methods may be useful in the treatment of non-metalic systems in some cases.

If fix_occupancy=FALSE the default value of this parameter is EDFT, otherwise it is NONE.
