which to replace pppm

Dear all,

I equilibrated a system using pppm to count the electrostatic interaction. But such kind of settings can not be used in nemd simulations to calculate the shear viscosity (not the muller-plate method, but using fix deform/ fix ave/spatial command). Since my original data file used such kind of settings, which other kind of method can replace pppm method to calculate the electrostatic interaction calculation in lammps2011? Thanks a lot.
