Hi Would you please say more about your system? How do you design / decide your simulation size of 100 surfactants +100 co-surfactants + 4000 water molecules?? How many surfactants will form a micelle? How many atoms does one surfactant have? How many atoms does one co-surfactant have? Do you sta

Hello there... I carried out simulations of mixture of cationic surfactants, fatty alcohols and water with various ratios of surfactant/alcohol. Usually for a system of 100 surfactants +100 co-surfactants + 4000 water molecules, it took 3 x 600 ps to see the micelles and other
