Hi all foamers,
I am a new entry in the world of OF and I'm trying to simulate the formation of a liquid meniscus between two flat surfaces (2D) as a process of merging of two drops.
I'm using InterFoam and I initialize two liquid half drops that intersect themselves, with their base on the two surfaces.

My domain dimension is very small (order of nanometers), and, working with these dimensions I encountered a strange behavior in the contact angle, in the sense it not respects my BC at the wall.
Dealing with micro dimensions I obtain a meniscus (but without the correct angle, that I imposed null), but when I try with nano dimensions the meniscus becomes a "cylinder" with infinite curvature (as if I Imposed alpha1=90)
Could someone help me?Any suggestion to solve this behaviour?... I can't understand what could be wrong in my case..?
Thanks in advance

Paolo
