About use of TAD command

Dear users and developers,

Does TAD command automatically raise the temperature of the system or it is necessary to langevin the atoms to the T_hi?

Have I to unfix nve atoms before?

Reading the documentation it seems it is automatic but the in lammps example (examples folder) it is used.

" fix 1 all nvt temp {thi} {thi} 0.1"

Thanks in advance,

Fernanda S Teixeira
