What does that mean? Charged particles with screened Coulomb? The PME 
algorithm will compensate for a net charge by a neutralizing background 
charge. You may also want to check this ref (Phys Rev E *70* pp. 051904 
(*2004*), http://folding.bmc.uu.se/david/oldpapers/bergh2004a.pdf) where 
we used an inhomogenous electron plasma. This was done in GROMACS but in 
a modified version.
