Liquid droplet displacement on a solid

Hello to everyone,

Currently I'm working on the displacement of a liquid on a solid, my goal is to enable the liquid to move from the initial phase to the initial phase (as shown in the attached files) with the increase of the contact angle of the liquid droplet.

I'm using the two phase laminar moving mesh with navier slip, and I define prescribed mesh displacement of 0 in r displacement of the rectangular bar of the solid and 0 n displacement for the spherical part of the solid that holds the liquid, and finally 0 to both r and z displacement for the walls and the inlet


Thanks for all
