Dear lammps users,
I am using the DLVO yukawa/colloid pair style and having a problem with the parameter settings.
According to the manual, the pairwise interaction is calculated according to this equation
where A = 2*PI*eps*eps0*kappa * R * psi^2; and eps*eps0 * kappa are constants.
It is known that for particle i, the radius is 6 nm and psi is +22mV; for Particle j, the radius is 20 nm and the psi is -10mV;
Based on these, how can I calculate the parameter A between i and j? Especially, the psi is in the different negative -10mV and positive +22mV.
Best regards
Ting
