Effect of Surfactants for interfacial tension

DPD is included in COGNAC. After the formation of an interface using two types of DPD particles, the surfactant is placed on the interface. After this, a system relaxation calculation is performed. As the density of the surfactant increases, the interface tension decreases, which indicates a breakdown of the interface shape.
