Dear lammps users,
I created my tabulated potential for born Mayer potential and ZBL potential , then I used "pair_style hybrid/overlay table linear 10000 ewald coul/long 10" command to combine the long range potential. I got very high temperature and pressure system.
I troubled shoot the problem by once involving the colombic range and once removing it, and I used the "pair_write" command, I found that the potential curve is nearly the same in both cases as if the tabulated potential contains a long range..
I read on the mailing list some of the colleagues were talking about excluding the colombic part from the potential, however my potentials are both for short ranges
Vb=Ae^-r/rho (A,rho are constants)
Vzbl= coloumbic potential* screening function
Can someone help me what am I missing here, is it a problem of cut off distances, should i exclude some terms from the potential or another thing?
Thank you in advance
