Hello, I'm trying to incorporate different advancing/recding contact angles for a water droplet surrounded by air on a solid surface. I'm using laminar two-phase flow, level-set method to model the air and water interfaces, and defining the contact angle explicitly as a constant in the wetted wall BC. What I want to do next, is apply different contact angles for advancing/receding motions of the droplets, as well as be able to capture contact angle hysteresis. Is there a way I can extract the contact line velocity, and apply dynamic contact angle as a function of that velocity?

Hello,
You can define the contact angle with the expression or variable within the parameter list.Then under the wetter wall, restate this variable or expression of interest. Next , Add parametric sweep under the Study, to run simulation for the various contact angle values you want. Also i hope this link below gives more information.
