Hi All,
I'm trying to calculate the DPD interaction parameter ( or chi parameter) for a system of oil/water/surfactant. I need to first obtain the solubility parameter for different pairs of material. in constructing the bead type, I need to have separate head and tail group of my surfactant. so I was wondering if for calculation of solubility parameter, do I have to break the structure into two files, one representing head group, and the other for tail group of the surfactant?
Thanks so much
