2d multi-phase dynamic mesh

Hi experts,

My case is a 2d multi-phase dynamic mesh for a piston cylinder arrangement partially filled with water and traps a certain amount of compressed air in a chamber. I can set the phases with mark regions options as attached in the picture

Due to piston motion, the water level should go up and down due to the change in volume which does not happen.

Can anyone help in this ?

By the way, I set the water density and speed of sound as user-defined function and the boundary between the inner cylinder and the annular one is set as interior. I have attached a copy with the main BC

Regards
Wael
