Hi all,
I am a beginner to COMSOL and using v3.5. I would like to model two phase flow in a mini capillary, for which I would like to first simulate a liquid droplet (say water) spreading to reach equilibrium contact angle over a solid surface.
As I am at very early stages of my learning, I request to guide me to model such flow cases.
Thanks for your time
Yours sincerely

Hi, I'm also a new leaner for COMSOL. I dont know how to do your modeling. But I used to run a simulation about ink droplet in FLUENT, in that case, the inlet boundary was defined as velocity as a function by time, so water can form a droplet in the air channel, I think in COMSOL, you also need to define the inlet of water phase by yourself to form a droplet. But about the contact angle part, I don't know how to set the boundary condition, sorry.
