Hey !
I've been trying to make a simulation of completely wetted or non-wetted walls (theta_w=0 or theta_w=pi) with phase field but it's always diverging. Have you ever tried and/or manage to do so ? How would you implement that plz ?
Thx in advance Joseph

I have tried complete wetting and other contact angles in Phase-field simulations. It works for me in most of the cases. The divergence is possibly due to inconsistent boundary conditions and defining phase-field features such as interface thickness and phase field tuning parameters. Go through this blog for more information on phase field modeling.
