Abstract

Based on Monte Carlo simulation of the contact line as a long-range elastic model, we develop tools relating substrate traps, trapping time and trapping length. We demonstrate the possibility of retrieving some information on the substrate topography from measurements of contact line motion, near the threshold in forced spreading or near the advancing angle in spontaneous spreading.
