Pinning/sticking of liquid droplet to wall surface
 

Hi All,
I am supposed to simulate a case where we have a moving wall and droplet is resting on it. The case I created is running fine, but the problem is the droplet doesnot stick to the surface. As soon as the wall starts moving (sinusoidal) the droplet leaves the surface and goes in upward direction.

I am using interDyMFoam.

Kindly suggest the ways so that droplet remains pinned/stick on surface
