analysis restart for lagrangian multiphase

mic

as i read in the user guide, after restarting the simulation with a steady air flow, i should obtain the solution in only one iteration. well, how to do that ? i set the analysis restart file, i set all the lagrangian simulations' parameters, then i've to give the same boundary conditions at the boundaries as in the steady solution or only by setting droplet properties, without flowing air, leaving empty the inlet/outlet windows? please help!
