Dynamic Mesh Zone UDF

      I am working on a project involving CFD within a curved cylinder. The piston also follows the curved cylinder instead of a crank-slider mechanism. I want to perform a dynamic mesh zone for piston in ANSYS ICE (fluent) in which instead of piston moving in z-axis, it has an angular motion around x-axis but at a distance equal to the radius of piston motion. Picture is attached below for your kind reference. I need to know how to specific the axis of rotation for piston in dynamic mesh. Please help me in the dynamic mesh modelling for the piston motion.
