1. I would to perform a Brownian dynamics simulations, and I used fix langevin along with fix nve as mentioned in LAMMPS documentations, but I have a question which is 

Brownian dynamics is used when implicit solvent is introduced in the simulation, whatever this solvent be it has a viscosity, so how I can introduce this viscosity with these commands ? 

2. How I can perform a simulation without boundaries ( No simulation box ) ?

3. How I can use a pair style coul/debye without a cutoff radius ( along with the previous question ) ?
